The Feast of the Assumption is a Marian feast day observed in both Catholic and Orthodox Churches on August 15 to commemorate the Blessed Virgin Mary being taken up (assumed) bodily into heaven.  Like all Marian feast days, the Assumption points us to experience more deeply truths about Christ.  On this day, Catholics celebrate Christ’s promise of eternal life and our own bodily resurrection. In normal conditions, this day is considered a Holy Day of Obligation for attending Mass. You can read more about the feast day on the University of Dayton Marian Library's All About Mary website or watch this short video to learn more about the importance of Mary in the Catholic Church.

Mid-Autumn Festival, a fall (or autumn) festival celebrated in China and other countries throughout East Asia. It is celebrated on the 15th day of the 8th month of the Chinese lunar calendar.  

Mid-Autumn Festival, also known as the Moon Festival, is the second largest festival in China, taking its name from the fact that it is always celebrated in the middle of the autumn season. The name, Moon Festival, comes from the moon being the roundest and brightest during this time of year. Ancient Chinese observed that the moon had a close relationship with changes in seasons and agricultural production. To give their thanks to the moon, and celebrate the full harvest, they offered sacrifice to the moon during autumn days. Common sacrifice is now demonstrated in late night gatherings to gaze at the beauty of the full moon.  

Some believe the full moon is a symbol of peace, prosperity, and a time for family gatherings. Celebrations for Mid-Autumn festival include outdoor reunions among friends and family to honor cultural and regional customs. Among these customs is eating large meals, burning incense, large performances, carrying or displaying brightly lit lanterns, and eating mooncakes. Mooncakes are the most popular celebration of the day. Mooncakes are traditional Chinese pastries made of flour with sweet or savory fillings. The mooncakes are a symbol of the family reunion, and the cake is traditionally cut into pieces that equal the number of people in a family.  

Holiest day for Jains. An eight day festival signifying human emergence into a new world of spiritual and moral refinement.

Rosh HaShana is the Jewish New Year, a high holy day, beginning 10 days of penitence and concluding  on Yom Kippur.

It is marked by 25 hours of fasting which starts an hour before Yom Kippur and ends after nightfall on the day. 

The observance of the birthday of the Islamic prophet Muhammad. It is celebrated with carnivals, large street processions, and the decorating of homes and mosques.

Jewish festival of booths (or tabernacles) and the fall harvest; takes name from  the booths used by Israelites during desert wanderings.

Dia de los Muertos, Day of the Dead, is a traditional celebration that originated within indigenous groups such as the Aztecs and Toltecs thousands of years ago. Life and death are at the center of this celebration as families gather to remember, share stories of, and leave gifts for their deceased loved ones. In this tradition, death is not seen as the end to one’s life, but a beginning to a new chapter of life. Family members gather together over a couple of days to prepare gifts and foods for the altar set in place to honor their loved ones. Altars (ofrendas) provide a physical space for others to express their love and reverence for their ancestors. One can typically find photos of the late family member, flowers, calaveras (sugar skulls), candy, home-cooked meals, small trinkets or toys, rosaries, crosses, and so much more. Often the items or foods placed at the altar are the known favorites of the person they are honoring and awaiting. Every one of these items are intentionally set on the altar and hold different meanings. Altars and decor for this celebration are often brightly colored, eccentric, and hold the essence of a fun party. Many may consider the party-environment to be a bit off putting given the circumstance of the celebration, but this is just another testament to the joy that comes alive as people come together to witness the beauty involved in the continued journey of life into death. 

We now celebrate Dia de los Muertos on November 1st - 2nd, but this has not always been the timeline for the tradition. The festivities initially took place over a period of time or a season as some may call it. It wasn’t until the 16th-century arrival of the Spanish conquistadors who thought the indigenous celebration had some essence of the Catholic faith traditions at the time. The tradition was then consolidated down to Nov. 1st - 2nd which, in the Catholic faith, is All Saints’ Day and All Souls’ Day. Many scholars say the more modern observances of Dia de los Muertos have indigenous roots with European influences likely as a result of colonization and growing assimilation. Celebrations of Dia de los Muertos have expanded beyond Mexico to other Latin American countries and to many LatinX-populated places in the United States. We are invited to learn more about the traditions and how they are similar and different to our Catholic beliefs. We are also invited to be cautious and reverent in any celebrations we may partake in on behalf of this tradition. Be mindful of cultural appropriation and use this as an opportunity to learn more about your own culture and beliefs around death as well.

On November 1st, the Roman Catholic Church celebrates the Solemnity of All Saints. On this day, all of the Saints, but especially those who do not have their own designated day, are remembered and appreciated for their witness of faith. Whether by humble witness, outlandish example, heroic death, or something entirely different, these are the ancestors in faith that are recalled in our Christian family memory and whose lives are used to inspire our personal paths to holiness.

Diwali is the ancient Hindu "Festival of Lights”.  Diwali is one of the most important Hindu festivals and also holds significance in the traditions of Sikhism and Jainism. Diwali celebrates the triumph of good over evil, purity over impurity, light over darkness. 

Diwali extends over five days, in which Hindu's and others prepare by cleaning, renovating and decorating their homes. Diwali night is spent praying, feasting, wearing fine clothing and exchanging gifts with family and close friends. It is a happy time where celebrants reflect on the spiritual significance of the triumph of good over evil. Representations of light are seen everywhere during Diwali! Fireworks, candles and lanterns are all major components of the celebration. It is believed that deceased relatives come back to visit families during the festival and the lights guide their way home. It is a holiday of giving, with small and large gifts alike bestowed to loved ones.
Diwali has ancient rituals and traditions rooted in Hinduism. It’s most popular in India, Nepal, Sri Lanka, Myanmar, and many other areas around the world. Although the nature of Diwali’s celebration varies from region to region, these unique traditions ensure a happy holiday filled with love, sharing, and self-reflection - a time of rejoicing and renewal.

Many are familiar with the Christian story of the birth of Jesus. But what does it mean? Christmas, the celebration of the incarnation, marks the revelation of God becoming human. The incarnation reveals a generous, courageous, loving God.  This act of love - becoming one with  us -  affirms the goodness of creation and the potential of humanity to embody love – as Jesus did with his life.   Christmas calls us to fully embrace Jesus’ presence among us, by fully embracing unconditional love. Put in the language of the season - we long to encounter and to embody true joy, peace, hope, and unity - love.

For Catholics, the Christmas season begins on the Eve of Christmas and extends until the Feast of the Baptism of the Lord, this year on January 10.  Christmas trees, nativity scenes, gift giving, worship and celebrations with family and friends (often with special foods reflective of family history and culture) are traditions of this season. 

The celebration of Kwanzaa consists of aspects of several different harvest celebrations that span the continent of Africa. Many celebrations include dances, African drums, a traditional meal, storytelling and poetry readings.

The tenth and last living prophet of the Sikhs, he passed the guruship onto the Sikh scripture, the Guru Granth Sahib, and the Sikh community, Guru Panth.

Buddhist celebration of the Enlightenment of Buddha, ca. 596 B.C.E.


"Spring Festival", as it’s referred to in China, is a multi-day celebration that emphasizes family, food, and other centuries old customs and traditions. While these customs and traditions vary from region to region, some elements are universal. For example, people will spend lavishly on gift giving, decoration, food, and clothing. It is also common for families to clean their houses in order to sweep away any ill-fortune. Windows and doors are often decorated with intricate hand cut paper designs and calligraphy representing popular new year's themes of "good fortune", "happiness", "wealth", and "longevity." On Lunar New Year's Eve, families gather together for a reunion dinner. Families will often end the night by setting off firecrackers. Early the next morning, children will pay respects to their parents, wishing them a healthy and happy new year, and in turn receive gifts. These gifts often come in the form of money placed in a red envelope, a traditionally fortuitous and beloved color.

To return home to take part in this dinner and other new year's activities is an expectation -- even an obligation -- for many, which results in the world's largest annual human migration. Millions of people will drive, fly, and/or take a train, enduring countless hours and days of difficult travel, to reach their ancestral homes to pay respects to their families.

The first day of Lent occurring forty-six days before Easter. Ash Wednesday derives its name from the practice of placing ashes on the foreheads of adherents as a sign of repentance. Lent is a Christian festival of preparation for Easter observed through reflection on the life and death of Jesus Christ.

Lent is a Christians season of fasting, reflection, and offering penance that lasts  40 days (Sundays not included) beginning on Ash Wednesday and ending on  either the evening of Maundy Thursday or on sundown of Holy Saturday (day  before Easter Sunday).

The days of Ayyám-i-Há, or “Days of Ha,” are devoted to spiritual preparation for the month long fast, Alá that follows. These days are festive times in the community, characterized by hospitality, charity, service and gift-giving. They are celebrated during the four or five days before the last month of the Baha’i year (which follows a lunar calendar).  During Alá, the period of fasting, Baha’is are obligated to suspend consumption of food and water from sunrise to sunset for 19 days.  The period of fasting ends with the celebration of Naw-Ruz on Mar 20 or 21.  Members of the UD community are invited to be conscious of those fasting during this time and can refer to UD’s practices for religious accommodation for suggestions on how to support one another or ask for support.  To understand more about the Baha’i tradition, please visit  


Holi is an annual holiday signifying the arrival of spring on the Hindu calendar. On the full moon, or Phalguna Purnima, people take to the streets to drench each other in colored powder and water. A carnival of laughter, play, music, dance and plenty to eat and drink ensues around the brightly colored hordes of people celebrating Holi. On the night before this joyful holiday, the ritual of preparing a Holika bonfire kicks off the activities with song, dance and preparation for the next morning. The burning fire symbolizes the defeat of Holika. The holiday thus celebrates the triumph of good, and makes way for the day of celebrating love, friendship, family and community. After a wild morning, evenings are spent gathering with loved ones.
Holi has ancient rituals and traditions rooted in Hinduism. It is most popular in India, where it is a public holiday in many states, but is also celebrated in Nepal, Pakistan, Bangladesh, and any other areas around the world influenced by Hindu culture. Although the nature of Holi’s celebration varies from region to region, its rich history means an enduring rejoice of love, color, spring and all things good and happy.  Find out more information about Holi here.

Commemorated at UD in February

The MAAFA, which means “great tragedy” in Kiswahili, refers to the Transatlantic Slave Trade period, where historians estimate that close to 12 million Africans were captured and brought to the Americas. Held in February, on the campus of the University of Dayton, students and community members are invited to journey through the MAAFA by engaging with cultural artifacts and stories of celebration and resilience. The Commemoration will also highlight a ceremony of reflection and healing, including musical performances, spoken word, communion, and a ritual of libations.


Ramadan takes place each ninth month according to the lunar Islamic calendar.  Ramadan is observed by Muslims all around the world as a month of increased devotion and self-discipline and is honored as the most sacred month of the year. During each day of Ramadan, Muslims fast from food and drink from sunrise to sunset.

Ramadan is regarded as one of the Five Pillars of Islam and a time for cleansing the soul and strengthening spiritual bonds.  The Arabic word for “fasting” (sawm) means “to refrain” and refers to refraining not only from food and drink but also negative actions, thoughts and words. A day of fasting consists of the first meal before dawn and is broken after sunset, typically with fruit juice or dates.  Although varied across nations, it is common in some Muslim countries to light the streets with lanterns and other lighting effects. Ramadan is also a time of increased devotion.  During Ramadan, Muslims spend additional time daily performing special prayers and in reading the Qur’an.

Eid al-Fitr, also called the “Feast of Breaking the Fast” marks the end of Ramadan. During Eid al-Fitr, it is common to dress in the finest clothing, offer presents to children, visit open areas and entertainment, perform prayer, spend time with family and friends and give a monetary donation to those in need or to the mosque.

Lent is a Christians season of fasting, reflection, and offering penance that lasts 40 days (Sundays not included) beginning on Ash Wednesday and ending on either the evening of Maundy Thursday or on sundown of Holy Saturday (day before Easter Sunday).

Bahá’i New Year.


Celebrated in March, Nowruz is the Iranian New Year which is celebrated worldwide. This ancient holiday coincides with the spring equinox, and is celebrated both as a secular holiday and a religious one by members of several different faiths. It remains a holy day for Zoroastrians. The Baha’i celebrate Naw Ruz as New Year’s Day, marking the end of the annual 19-day fast. For Baha’i it is one of the nine holy days of the year when work is suspended and children are exempted from attending school. 

Nowruz, also known as the Persian New Year, marks the first day of the first month (Farvardin) in the Iranian calendar as well as the beginning of spring in the Northern Hemisphere. Families gather together to observe the rituals once the sun crosses the celestial equator and equalizes night and day. Iranians consider Nowruz as their biggest celebration of the year. Before the new year, some people start cleaning their houses (Khaane Tekaani), and may even buy new clothes.

A major New Year ritual is setting the "Haft Seen" with seven specific items. In ancient times, these seven items symbolized the creations and the holy immortals protecting them. Today they are changed and modified but some have kept their symbolism. These seven items usually are referred to as the seven “S’s”: Seeb (apple), Sabze (green grass), Serke (vinegar), Samanoo (a meal made out of wheat), Senjed (a special kind of berry), Sekke (coin), and Seer (garlic). Sometimes instead of Serke they put Somagh (sumak, an Iranian spice). Zoroastrians today do not have the seven items, but they have the ritual of growing seven seeds as a reminder that this is the seventh feast of creation, while their sprouting into new growth symbolized resurrection and eternal life to come. Baha’i celebrate this day as the Springtime of humanity's rebirth.

Purim is a festival that commemorates the deliverance of the Jewish people living  throughout the ancient Persian Empire from persecution by Haman the Agagite. 

Begins Christian Holy Week, the last week of Lent and the final week before Easter.  It refers to the palms that people spread on the road as Jesus entered Jerusalem  to celebrate the feast day of Passover. 

Celebrated before Good Friday, Christians commemorate the institution of the  Eucharist as the Body and Blood of Jesus Christ and the institution of the  sacrament of priesthood. 

Celebrated on the Friday before Easter, Christians remember the crucifixion of  Jesus and related events. 

Easter and the Paschal Triduum

For Christians, Easter celebrates the resurrection of Jesus - the triumph of life’s victory over death. Easter is a celebration of hope.  God promises victory over death through faith in Jesus, who is the true light of the world.  Because of Jesus, Christians look forward to their own everlasting life.  The victory of life over death also has significance in daily life, in the ways that Christians grow as disciples of Jesus, who accompanies all through the joys and challenges of living in faith.  The Easter season lasts 50 days, through the celebration of Pentecost.  It is a joyful season, signified also by the onset of spring. 

Easter is always on a Sunday.  For most Christians, it falls on the First Sunday on or after the spring equinox.  Orthodox Christians use a different calendar and method to determine the date.  This is why there are two Easter Sundays on the calendar.

In the Catholic tradition, the celebration of Easter follows the Paschal Triduum, “the three days.” These are the summit of the liturgical year, in which the mysteries of the life, death, and resurrection of Jesus are celebrated.  Holy Thursday recalls the institution of the Eucharist and its expression in radical service in the Mass of the Lord’s Supper.  A ritual of foot washing is a part of the liturgy for this day.  Good Friday is a solemn day of fasting for Catholics, who venerate the cross (with a touch or a kiss) as they enter into the Lord’s Passion.  The fast continues through the eve of Holy Saturday.  The Easter Vigil, which occurs after dark, celebrates the light of Christ entering salvation history - God’s work in the world from the time of creation.  New members of the faith community are welcomed through baptism on this night.  The celebration of Easter begins with this vigil. 

There are some common and some unique ways of observing Easter among different Christian traditions.  Families worship together, share lamb cakes, hunt for Easter eggs, and more.  The following resources offer more information about the Paschal Triduum, Easter and its origins, and the various ways it is celebrated among Christians.

An Islamic festival of sacrifice that commemorates the faith of Abraham; also a  memorial to the dead. One of two major festivals; the other being id al-Fitr.

Sikh New Year and spring harvest festival 

Commemorates the declaration of Baháúllah to his followers in 1863. The first,  ninth and twelfth days of Ridvan are major Baha'i holy days. 


Passover, celebrated by Jewish people, celebrates God’s role in bringing about both past and future redemption.  It is one of the most important Jewish festivals of the year.  The high point of this festival is the Sedar Meal, when the story of the Exodus is recounted, the time when Moses led the Ancient Israelites into freedom, following years of slavery in Egypt.  

The Seder Meal is a religious service celebrated by families and communities around a dinner table. Special foods are prepared and shared for the ritual of retelling the Exodus story, which Jews are commanded to teach their children.  The Seder plate contains: bitter herbs (often horseradish) to represent the harshness of slavery; charoset, a sweet brown mixture that represents the mortar and brick used by Hebrew slaves; a shankbone representing the passover lamb; a vegetable such as parsley which is dipped in salt water to represent tears of slavery as well as hope and renewal; a roasted or hardboiled egg representing spring and the circle of life; and three pieces of Matzoh representing the unleveaned bread Ancient Hebrews took with them when fleeing Egypt. The themes of physical and spiritual freedom are emphasized, for it is in this freedom that Jewish ancestors received God’s law, the Torah, on Mount Sinai.  The theme of creation is also emphasized through symbols of spring, rebirth, and renewal. Jews journey towards freedom and redemption in their individual lives as well as their lives as a people.  Along with the telling of the Exodus story, families and friends enjoy song, community and conversation about current events, many emphasizing continued commitment to fight for oppressed people’s freedom around the world.   

Christians who seek to celebrate a Seder are wise to accompany Jewish friends or to seek out and attend an Interfaith Seder held in a Jewish community, rather than to appropriate it themselves as an element of Christian history, which it is not.   


Known as Pascha, the Greek word for “Passover,” Easter in the Eastern Orthodox Church (or Orthodox Christian Church) celebrates “the eternal Passover from death to life from earth to heaven.” It is the feast of the Resurrection of the Lord and Savior Jesus Christ. This feast of feasts is the most significant day in the life of the Church. Easter follows Great Lent which takes place for 40 days, starting on Clean Monday and ending on Lazarus Saturday—when Jesus raised Lazarus from the dead. Palm Sunday and Holy Week follow Lazarus Saturday, for a total of 48 days of preparation for the resurrection.

Orthodox Christianity follows the “Julian Calendar” which was designed by Julius Caesar in 45 B.C. Easter in the Orthodox Church always follows the Jewish holiday of Passover because, according to the New Testament, the crucifixion and resurrection of Christ took place after he entered Jerusalem to celebrate Passover. 

Orthodox Easter is celebrated with great joy. A traditional Easter greeting among Orthodox Christians is the Paschal greeting. It begins with the phrase “"Christ ​is Risen!" The response is "Truly; He is Risen!" 

In the Orthodox tradition, eggs are a symbol of new life. Early Christians used eggs to symbolize the resurrection of Jesus Christ and the regeneration of believers. At Easter, some traditions dye eggs red to represent the blood of Jesus that was shed on the cross for the redemption of all humans.

The American Civil War began on April 12, 1861 and lasted until General Robert E Lee surrendered in Virginia on April 9, 1985. The war was fought to protect “State’s rights”--specifically, the right to continue owning humans born into enslavement.

On January 1, 1863 President Abraham Lincoln signed the Emancipation Proclamation which promised freedom for those enslaved in “rebellious states” dependent upon the victory of the Union Army. Texas, however, continued battling until May 13, 1865.

It was on (or about, hence the “teenth”) June 19, 1865 that the enslaved in Texas were finally free. Slavery was abolished (with exceptions) by the ratification of the 13th Constitutional amendment on December 6, 1865.

The first Juneteenth celebration was June 19, 1866 and was originally called “Jubilee Day”. Jubilees are days of religious/spiritual significance. Leviticus 25:1-13 orders the year of Jubilee to be a time of restoration for the land and for those who had lost their property and freedom for those who had been enslaved. Congress passed a resolution establishing Juneteenth as a national holiday; President Biden signed it into law on June 17, 2021. 

While Juneteenth celebrations vary among communities, there is an abundance of food, song, dance, art and speeches with past and present-day relevance. The Juneteenth flag is often displayed as a sign of victory and unity.

Food traditions often include:

  • Cooking over an open fire remembering how the enslaved were forced to cook their own foods outside.
  • Red foods and drinks in remembrance of the millions who died during the four-hundred-year captivity of Africans and their descendants.
  • Side dishes of green foods and those that are “rich” (such as macaroni and cheese) symbolizing growth and prosperity.

Song, dance and art celebrate diverse culture, spirituality, accomplishment and struggle. Speeches often center around the reminder that the struggles for recognition and inclusion persist for Black/African Americans.

Listed below are a few ways an “other” person can celebrate Juneteenth. The most helpful way to honor this day of Jubilee as an “other” is to do the personal, religious, social and political work of antiracism throughout the year.

  • Financially sponsor an event without expectation of inclusion in planning or recognition of the donation. 
  • Attend a celebration in your community and be prepared to make purchases from the vendors present. Be aware to not appropriate clothing/hairstyles in attendance. African attire, jewelry and hairstyles have spiritual and cultural meaning and as such should not be worn as trends, costumes or accessories. 
  • Support Black owned businesses throughout the year. In addition to restaurants and boutiques, include Black authors in your reading list for students/staff, invite Black authors for book talks and speaking engagements. 
  • Become more aware of the political/social struggles in our community and nation. Pick an issue to champion following the leadership of and in partnership with the Black community. 

Although Juneteenth is a day of Jubilee, it should be noted that neither the enslaved nor their descendants have been made whole as prescribed by the ancient text. Resistance against oppression and the fight for justice persists among the joyous celebration of life, culture and resilience.
