2027 Jewish Holidays: Dates, Calendar & Observances

Below is a comprehensive guide to the 2027 Jewish Holidays: dates, calendar placement, and observances. Because the Jewish calendar is based on the lunar-solar cycle, the Hebrew calendar year that overlaps with 2027 Gregorian dates is 5787/5788. This article presents the Hebrew dates for the holidays in 2027 and provides the approximate Gregorian windows so families, students, travelers, and interested readers can plan with clarity. Note that exact local dates may vary by community and by whether you follow Israel or diaspora practice (especially for holidays that begin at sunset and span into the next day).

To appreciate the layout of the 2027 Jewish holidays, it helps to understand a few core ideas about the Jewish calendar:

• Hebrew year 5787 is a leap year. This means there is an extra month (Adar I and Adar II), which shifts where Purim and Passover land within the year. Purim in 2027 occurs in Adar II (14 Adar II 5787), and Passover in 2027 lands in Nisan 5787 (15 Nisan 5787).
• Hebrew year 5788 runs from Rosh Hashanah 5788 (early fall 2027) through Tishrei 5788 (late fall 2027). This year is not a leap year, but it hosts the continued sequence of holidays after Rosh Hashanah and Yom Kippur.
• Rosh Hashanah and the Holy Days that surround it begin in the early autumn and are observed for two days by many communities outside Israel, while Israel often observes one-day observances for certain holidays. This is a general pattern you will see mirrored in 2027’s listings.
• Observances include both the biblical or rabbinic chagim (festivals) and the notice of special fasts or commemorations that reoccur year to year (e.g., Tzom Gedaliah, the 9th of Av, the 17th of Tammuz).

What follows is a practical layout of the major holidays during 2027, aligned with the Hebrew calendar and accompanied by the probable Gregorian windows. Bolded terms indicate the holiday name and the central observance.

Tu BiShvat (New Year for Trees) and early-year observances

• Tu BiShvat: 15 Shevat, 5787
• Approximate Gregorian window: February 2027 (often late January to mid-February, depending on locale).
• Overview: Tu BiShvat is a seasonal celebration of trees and agriculture in Israel and diaspora communities. In many places it is observed with fruit symbolism, plantings, and environmental education. Some families hold a small seder or gather for fruit-based meals. The holiday is less about fasting or ritual prohibitions and more about renewal and gratitude for the cycles of nature.

Purim in 2027 (the leap-year year’s Purim day)

• Purim: 14 Adar II, 5787
• Approximate Gregorian window: March 2027
• Overview: Purim celebrates the deliverance of the Jews in the time of Esther. It is a day of reading the Megillah, giving gifts of food (mishloach manot), giving charity (matanot la’evyonim), and festive meals. In leap years, many communities observe Purim in Adar II (the second Adar) and some celebrate Shushan Purim as a secondary festive day. For families with children, costumes and playful celebrations are common, and charitable giving is emphasized.

Passover (Pesach) 2027 in the leap year context

• Passover: 15 Nisan, 5787
• Approximate Gregorian window: April 2027
• Overview: Passover commemorates the Exodus from Egypt and includes the Seder on the first two nights (in most communities outside Israel, two Seders are observed; Israel often observes one). Dietary restrictions (avoidance of chametz) are central for the duration of Passover, typically seven days in Israel and eight days in the diaspora. TheOmer counting begins on the second night of Passover and continues for 49 days until Shavuot. In 2027, the holiday sits firmly in late winter/early spring.

Shavuot and the spring festival

• Shavuot: 6 Sivan, 5787
• Approximate Gregorian window: May/June 2027
• Overview: Shavuot marks the giving of the Torah on Mount Sinai. Many communities observe all-night Torah study (Tikun Leil Shavuot) and dairy foods as a key culinary motif. The holiday closes the Omer count that begins with Passover.

Rosh Hashanah 5788 (New Year 2027 in the Hebrew calendar)

• Rosh Hashanah: 1–2 Tishrei, 5788
• Approximate Gregorian window: September 2027
• Overview: The two-day observance begins the Ten Days of Repentance leading to Yom Kippur. It is a time for reflection, prayer, and blowing the shofar. In many communities, the sound of the shofar on the first day is a solemn call to introspection, and special services are held in synagogues around the world. Foods like apples dipped in honey symbolize wishes for a sweet new year.

Yom Kippur (Day of Atonement) 5788

• Yom Kippur: 10 Tishrei, 5788
• Approximate Gregorian window: September/October 2027
• Overview: The holiest day in the Jewish year, observed by fasting, intensive prayer, confession, and collective atonement. The day is marked by long synagogue services, Kol Nidre on the eve, and a concluding Ne’ilah service as the fast ends at nightfall. Families and communities often gather for prayers and study, and many people observe a day of rest.

Sukkot, Shemini Atzeret, and Simchat Torah 5788

• Sukkot: 15–21 Tishrei, 5788
• Shemini Atzeret / Simchat Torah: 22–23 Tishrei, 5788
• Approximate Gregorian window: September/October 2027
• Overview: Sukkot is the festival of tabernacles, commemorating the Israelites’ journey in the wilderness. The holiday cycle includes building and dwelling in sukkot (temporary booths), waving the lulav and etrog, and special readings. Shmini Atzeret and Simchat Torah celebrate the Torah with joyous processions and dancing with Torah scrolls. In Israel, some customs differ slightly from the diaspora, but the overall arc remains the same: harvest thanksgiving, gratitude for protection, and communal rejoicing.

Hanukkah 5788

• Hanukkah: 25 Kislev–2 Tevet, 5788
• Approximate Gregorian window: December 2027
• Overview: The Festival of Lights commemorates the rededication of the Second Temple and the miracle of oil. Hanukkah is observed by lighting the menorah for eight nights, playing dreidel, eating fried foods like latkes and sufganiyot (jelly-filled donuts), and giving small gifts or gelt. The dates slide into December and can touch January depending on lunar alignment. Interpretations and customs vary among communities, but the central symbolism remains the same: perseverance, gratitude, and the triumph of light.

Beyond the major festivals, the Jewish year includes several fast days and commemorative moments that recur on a predictable cycle. In 2027, you can expect the following to be observed in many communities, though exact observance might vary by tradition and locality:

• Tzom Gedaliah (fast day after Rosh Hashanah, 3 Tishrei): a minor fast that commemorates Gedaliah’s murder and reflects on political and social leadership. This fast is observed by many communities in the diaspora and in Israel alike.
• Asarah B’Tevet (10 Tevet): a minor fast that marks the siege of Jerusalem; observed by many for reflection and fasting, typically during the winter months.
• 17th of Tammuz: a fast day that historically marks the breach of the walls of Jerusalem prior to the destruction of the Second Temple; observed as a day of fasting for many communities leading into the three weeks prior to Tisha B’Av.
• 9th of Av (Tisha B’Av): a major fast day commemorating the destruction of the First and Second Temples; observed with special prayers, readings, and mournful reflections. This day typically falls in the summer months and is a focal point of lamentation and introspection for many Jewish communities.

Observances around these fasts include adjustments to work and school, special synagogue services, and targeted readings. While not all communities observe every fast, these dates anchor annual cycles of memory and repentance that are central to the Jewish liturgical calendar.

One practical dimension of the 2027 Jewish holiday calendar is the difference between diaspora practices and Israel practices. In Israel, some holidays may be observed for a single day (one-day Yom Tov is common in Israel for certain holidays), whereas diaspora communities often observe two full days of Yom Tov out of caution and tradition. This distinction influences:

• Length and timing of holiday observances in schools and workplaces
• Timing of Shabbat and festival candles, which may shift by one day depending on location
• Observance of special prayers, liturgical additions, and Torah readings in synagogues

When planning travel, family gatherings, or study, it’s wise to consult your local synagogue or community calendar for the precise schedule in your area. Even in the same city, Ashkenazi and Sephardi communities may have slight variations in customs, blessings, and liturgical options.

• Plan ahead for Rosh Hashanah and Yom Kippur: Book travel, accommodations, and synagogue seating early if you plan to be in a major city or a location with holiday crowds. Consider preparing for two days of observation if you will be following diaspora customs outside Israel.
• Observe the Seder plans for Passover: If you are in a diaspora community, reserve spaces for Seder gatherings well in advance. If you host, create a guest-friendly Passover menu that accommodates common dietary restrictions and kosher requirements. Remember that Omer counting follows Passover.
• Hanukkah logistics: Hanukkah’s December window can impact travel plans and gift-giving. Many families host small gatherings, light menorahs, and prepare festive foods with seasonal ingredients like potatoes, apples, and doughnuts.
• Purim considerations: If you attend Purim celebrations with children, plan costumes and safe party activities. Purim is a time for charity and communal joy, alongside the reading of Megillah and merriment.

Whether you are studying for a class, writing about Jewish festival observances, or planning your 2027 family calendar, these dates offer a robust framework for understanding the year’s rhythm of feasts, fasts, and reflections.

Across the year, these holidays carry recurring themes that knit together the spiritual and cultural fabric of Jewish life. Here are some highlights to frame 2027 Jewish Holidays in terms of meaning and practice:

• Rosh Hashanah centers on repentance, renewal, and the sound of the shofar. It is a time to reflect on personal goals, relationships, and community ties as a new year begins.
• Yom Kippur is the culmination of the Days of Awe, featuring fasting, prayer, and atonement. It invites individuals and communities to seek forgiveness and restoration of balance.
• Sukkot emphasizes gratitude for harvest, shelter, and hospitality. Dwelling in a sukkah invites a tangible sense of impermanence and dependence on community.
• Hanukkah celebrates resilience and light, turning a historical miracle into a season of family gatherings and creative lighting traditions.
• Purim blends joy and relief with memory, charity, and acts of courage. It is one of the most festive holidays on the calendar, featuring costumes and revelry in many communities.
• Passover is a central festival of freedom and memory, with the Seder guiding families through stories of liberation and a shared meal that reinforces identity and history.
• Shavuot links the joy of harvest with the revelation of the Torah, often celebrated with learning late into the night and study sessions.

Understanding these themes helps readers grasp not only the dates but the spiritual rhythm of the year in 2027 Jewish Holidays, and how different communities may emphasize various aspects depending on tradition and local practice.

1. Mark Hebrew dates first in your planning tools. The Hebrew calendar determines when holidays fall in 2027, with the annual rhythm shaped by leap years and lunar cycles.
2. Note the two-day vs one-day observance pattern in diaspora vs Israel, especially for Rosh Hashanah, Sukkot, and Passover. Always verify local calendars.
3. Include the Omer count after Passover if you observe it, as the counting of the Omer continues for 49 days until Shavuot.
4. Prepare for fasts and commemorations by adjusting work schedules, school calendars, and travel plans in advance where possible.

For educators, writers, and content teams, this structure enables a clear and accessible presentation of the year’s 2027 Jewish Holidays, with enough context to explain both the numerical dates and the underlying traditions.
