The Islamic New Year marks the beginning of a new year in the Islamic lunar calendar. It commemorates the Hijrah, the migration of the Prophet Muhammad from Mecca to Medina in 622 CE, which marks the start of the Islamic calendar. Many Muslims observe the day with prayer, reflection, and remembrance rather than large celebrations.

Ashura, observed on the 10th day of the Islamic month of Muharram, holds distinct yet overlapping meanings within Islam. For Sunni Muslims, it typically commemorates the day God saved Moses and the Israelites from Pharaoh, and it is often marked by voluntary fasting. For Shiʿa Muslims, however, it is a solemn day of mourning for the martyrdom of Husayn ibn Ali at the Battle of Karbala in 680 CE.

Gahambar Maidyoshem is one of the six seasonal festivals in Zoroastrianism, observed in late spring and associated with the creation of the sky in Zoroastrian cosmology. It expresses gratitude for the natural world as a sacred and ordered creation, emphasizing harmony between humanity and the environment. The festival is marked by communal meals and acts of generosity, highlighting values of equality, charity, and shared responsibility within the community.

Tisha B’av is a solemn Jewish fast day that commemorates the destruction of the First and Second Temples in Jerusalem, along with other tragedies in Jewish history. It is observed with a 25-hour fast, mourning rituals, the reading of the Book of Lamentations, and sitting on the floor or low stools in grief. The day reflects themes of loss, exile, and the hope for future redemption and rebuilding.

Mawlid an-Nabi commemorates the birth of the Prophet Muhammad, observed by many Muslims on the 12th day of Rabi al-Awwal in the Islamic calendar (with some, particularly among Shia Muslims, marking it on the 17th). It is often celebrated with gatherings, the recitation of poetry and devotional songs praising the Prophet, charitable giving, and shared meals, as an expression of love and reverence for him. Observance varies across the Muslim world, and some communities choose not to mark it, reflecting differing scholarly views on the practice.

Raksha Bandhan is a Hindu festival celebrating the bond between brothers and sisters, typically observed on the full moon day of the month of Shravana (usually in August). The central ritual involves a sister tying a sacred thread called a rakhi around her brother's wrist, symbolizing her love and prayers for his wellbeing, while the brother offers a gift and pledges to protect and support her. Though rooted in Hindu tradition, it is widely celebrated across South Asia and has grown to embrace broader expressions of affection, protection, and kinship beyond strictly sibling relationships.

Paryushan is the most important annual festival in Jainism, a period of spiritual reflection, fasting, prayer, and study observed over eight days by Svetambara Jains. It is a time for practicing the core Jain values of nonviolence, self-discipline, and the purification of the soul, often culminating in heartfelt repentance and the seeking of forgiveness from all beings. The festival concludes with Samvatsari (or Kshamavani), on which Jains ask pardon for any harm caused, expressed in the phrase "Micchami Dukkadam," meaning may any wrongdoing be forgiven.

Rosh Hashanah is the Jewish New Year, observed on the first and second days of the month of Tishrei (usually September), commemorating the creation of the world and beginning the High Holy Days. It is a time of prayer, reflection, and repentance, marked by the sounding of the shofar (a ram's horn), special synagogue services, and the eating of symbolic foods such as apples dipped in honey to express hopes for a sweet year ahead.

Gahambar Paitishem (also spelled Paitishahem) is one of the six seasonal festivals, known as Gahambars, observed in Zoroastrianism, each celebrating a stage of the agricultural year and an aspect of creation. Paitishem marks the bringing in of the harvest, typically falling in mid-September, and is traditionally a time of communal gathering, shared feasting, prayer, and charity, reflecting the Zoroastrian values of generosity and fellowship. Like the other Gahambars, it expresses gratitude to Ahura Mazda for the bounty of creation and emphasizes community, with the food and offerings shared freely among all who attend, regardless of means.

Ganesh Chaturthi celebrates the birth of Lord Ganesha, the elephant-headed Hindu deity revered as the remover of obstacles and the patron of beginnings, wisdom, and good fortune. Observed over ten days in the month of Bhadrapada (usually August or September), it is marked by the installation of Ganesha idols in homes and public pavilions, daily prayers and offerings of sweets such as modak, and devotional singing. The festival concludes with Visarjan, the joyful procession in which the idols are immersed in water, symbolizing Ganesha's return home and the cycle of creation and dissolution.

Das Lakshan is the ten-day festival observed by Digambara Jains as their principal annual occasion for spiritual reflection and purification, typically falling in the month of Bhadrapada (around August or September). Each of the ten days is dedicated to contemplating one of the ten supreme virtues, or dharmas, such as forgiveness, humility, truthfulness, and self-restraint, which guide the soul toward liberation. The observance is marked by fasting, scriptural study, worship, and seeking and granting forgiveness expressed through the phrase "Uttam Kshama," may any wrongdoing be forgiven.

Yom Kippur, the Day of Atonement, is the holiest day in the Jewish calendar, observed on the tenth day of Tishrei (usually September or October) as the culmination of the High Holy Days that begin with Rosh Hashanah. It is marked by a full day of fasting, intensive prayer, and repentance, during which the faithful seek forgiveness for wrongdoing and reconciliation with God and with one another. Tradition holds that on this day one's fate for the coming year is sealed, making it a solemn time of reflection, atonement, and spiritual renewal, often concluded with the sounding of the shofar.

Mabon is a modern Pagan and Wiccan festival celebrating the autumn equinox (usually around September 21st–23rd), one of the eight sabbats on the Wheel of the Year, marking the point when day and night stand in balance. It is observed as a harvest thanksgiving, a time to express gratitude for the fruits of the season and to reflect on themes of balance, reciprocity, and preparation for the coming darker half of the year. The name Mabon, drawn from a figure in Welsh mythology, was popularized in the 1970s, and the festival is often marked with seasonal foods, gatherings, and rituals honoring the second harvest.

Sukkot, the Feast of Tabernacles, is a Jewish festival beginning on the 15th day of Tishrei (usually September or October), shortly after Yom Kippur, and lasting seven days. It commemorates the forty years the Israelites spent dwelling in temporary shelters during their journey through the wilderness, and is observed by building and eating (and sometimes sleeping) in a sukkah, a temporary hut roofed with natural materials. It is also a harvest festival of joy and gratitude, marked by the gathering and waving of the four species (lulav and etrog), hospitality, and celebration, expressing thanksgiving for the autumn harvest and trust in divine providence.
