Understanding the Jewish calendar

The Jewish calendar follows the lunar cycle, which is why Jewish holidays fall on different Gregorian dates each year. While the Hebrew dates stay the same, their place on the Gregorian calendar shifts from year to year.

The year covered in this guide is 5787, which begins at sundown on Friday, September 11, 2026, with Rosh Hashanah and continues through October 1, 2027.

Unlike a standard Gregorian year, 5787 is a Jewish leap year. An extra month, Adar I, is added before Adar II to keep the lunar calendar aligned with the seasons. As a result, holidays from Purim onward occur several weeks later than they do in most years.

High Holidays (Yamim Noraim)

The Jewish calendar includes days of celebration, remembrance, pilgrimage festivals, and public fasts. Some are widely observed with family meals and synagogue services, while others are marked by fasting or special prayers. Below you’ll find every major Jewish holiday in chronological order throughout Hebrew year 5787.

The High Holidays begin the Jewish year and are among the most significant dates in the Jewish calendar. Rosh Hashanah celebrates the Jewish New Year and begins a period of reflection known as the Ten Days of Repentance. It concludes with Yom Kippur, the Day of Atonement, which is considered the holiest day of the year.

These holidays are observed similarly in both Israel and the Diaspora, with Rosh Hashanah lasting two days everywhere.

Why Jewish holiday dates change every year

If you’ve ever wondered why Passover falls in April one year and later in another, or why Hanukkah sometimes begins in early December and other years starts in late November, the answer lies in the Jewish calendar.

Unlike the Gregorian calendar, which is based on the Earth’s orbit around the sun, the Jewish calendar follows the lunar cycle. Each Hebrew month begins with a new moon, making the Jewish year approximately 11 days shorter than a solar year.

To keep holidays in their proper seasons, the Jewish calendar adds an extra month seven times during a 19-year cycle. This creates a leap year, ensuring that holidays like Passover always remain in the spring.

Hebrew year 5787 is one of these leap years. It includes an additional month, Adar I, before Adar II, which pushes holidays from Purim onward several weeks later than they appear in most years.

Although the Gregorian dates change every year, the Hebrew dates remain constant. For example, Rosh Hashanah always begins on 1 Tishrei, while Passover always begins on 15 Nisan.

Curious how the whole system works? How the Hebrew Calendar Works covers the months, leap years, and how the two calendars align.

Israel vs. Diaspora observance

Most Jewish holidays are celebrated on the same Hebrew dates around the world, but some festivals are observed differently in Israel and in Jewish communities outside Israel.

These differences date back centuries, when communities living far from Jerusalem could not always receive confirmation of the new month in time. To ensure holidays were observed correctly, an additional festival day became customary in the Diaspora. Today, many Jewish communities continue to follow this tradition.

The main differences are:

Passover (Pesach)

Israel: 7 days. Diaspora: 8 days.

Shavuot

Israel: 1 day. Diaspora: 2 days.

Sukkot

The first days are observed the same way everywhere, but the ending differs. In Israel, Shemini Atzeret and Simchat Torah are celebrated together on the same day. In the Diaspora, they are celebrated on separate days, extending the holiday by one day.

Rosh Hashanah

Rosh Hashanah is unique because it lasts two days both in Israel and throughout the Diaspora.

If you’re planning a calendar, traveling, or coordinating events with family in different countries, these differences are important to keep in mind.

Create a personalized Jewish holiday calendar

A list of holiday dates is useful when you need to check a specific date. A personalized calendar is useful every day.

With CultureSync, you can create a printable calendar that includes the Jewish holidays you observe alongside the events that matter in your own life. You can choose exactly which holidays to include, then add:

  • Birthdays
  • Anniversaries
  • Memorial days
  • School events
  • Vacations
  • Personal reminders

If your family celebrates more than one tradition, you can also combine Jewish holidays with Christian, Chinese, and national holidays on the same calendar.

The result is a calendar that’s designed for your family, not a generic list of holidays.

In the Jewish calendar, each new day begins at sundown rather than at midnight. This tradition comes from the biblical account of creation, where each day is described as "evening and morning." As a result, every Jewish holiday begins on the evening before the Gregorian date typically listed on calendars.

The Jewish calendar is based on lunar months rather than the solar year used by the Gregorian calendar. While the Hebrew dates remain the same every year, the corresponding Gregorian dates shift. Leap years, like 5787, add an extra month to keep the calendar aligned with the seasons.
