Rosh Hashanah is one of the most important holidays in the Jewish calendar, marking the Jewish New Year. It is a time for reflection, prayer, and the renewal of one’s faith. But for those less familiar with Jewish traditions, one common question arises: Is Rosh Hashanah always on the same day? The answer is both yes and no, depending on how one views the calendar. In this article, we will explore how the Jewish calendar works, why the dates of Rosh Hashanah vary, and how this significant festival is observed in the UK.
Understanding the Jewish Calendar
The Lunisolar Calendar
Unlike the Gregorian calendar, which is based solely on the solar year, the Jewish calendar is a lunisolar system. This means it takes both the phases of the moon and the solar year into account. The Jewish months are based on the moon’s cycles, and each month begins with the new moon. A lunar month lasts approximately 29.5 days, meaning a lunar year of 12 months is about 354 days long—11 days shorter than the solar year.
To keep the Jewish holidays aligned with their appropriate seasons, an extra “leap month” is added seven times in a 19-year cycle. This additional month, called Adar II, helps to balance the shorter lunar year with the solar year. Without this adjustment, holidays like Passover (which must occur in the spring) would gradually shift throughout the year, falling in different seasons over time.
The Role of Rosh Hashanah in the Jewish Calendar
Rosh Hashanah, which means “Head of the Year” in Hebrew, falls on the first day of the Jewish month of Tishrei. Tishrei is the seventh month of the Jewish calendar, yet it marks the beginning of the Jewish civil year. This might sound confusing, but it’s because the Jewish calendar has multiple “new years.” Rosh Hashanah is considered the new year for the purpose of counting years, just as the Gregorian New Year on January 1 marks the beginning of a new year for civil purposes.
Because the Jewish calendar follows lunar months, Rosh Hashanah does not fall on the same day of the Gregorian calendar each year, but it always falls on the first and second days of Tishrei in the Jewish calendar.
Why Does Rosh Hashanah Seem to Move?
Variation in the Gregorian Calendar
The Gregorian calendar, used in the UK and most of the world, is based on the solar year and has 365 days (or 366 in a leap year). Since the Jewish calendar is approximately 11 days shorter than the Gregorian calendar, the date of Rosh Hashanah shifts each year when compared to the solar-based calendar.
For example, Rosh Hashanah might fall in mid-September one year and early October the next. While the holiday always occurs on the first day of Tishrei in the Jewish calendar, its corresponding Gregorian date varies. Typically, Rosh Hashanah falls between September 5 and October 5, but the exact date can fluctuate within this range depending on the year.
Leap Years and the Jewish Calendar
As mentioned earlier, the Jewish calendar adds a leap month, Adar II, seven times in a 19-year cycle. The inclusion of this extra month helps keep the holidays aligned with the seasons, but it also contributes to the shifting of Rosh Hashanah’s date on the Gregorian calendar. In years with a leap month, Rosh Hashanah will be “pushed” later in the year. For example, if Rosh Hashanah falls in early September one year, it may occur in late September or early October the following year due to the leap month.
This shifting of dates is why Rosh Hashanah appears to “move” on the Gregorian calendar, even though it remains fixed in the Jewish calendar.
Observing Rosh Hashanah in the UK
Jewish Communities in the UK
Rosh Hashanah is a significant religious observance for Jewish communities around the world, including in the UK. The United Kingdom has a longstanding Jewish population, with large communities in London, Manchester, and other major cities. The Jewish community in the UK is diverse, encompassing Orthodox, Conservative, Reform, and Liberal denominations, each with its own customs and traditions for celebrating Rosh Hashanah.
For many British Jews, Rosh Hashanah is a time for family gatherings, attending synagogue services, and enjoying festive meals. The holiday is marked by special prayers, including the sounding of the shofar (a ram’s horn), which is a central element of the Rosh Hashanah service. The shofar is blown 100 times during the holiday to symbolize awakening, reflection, and the call to repentance.
Traditional Rosh Hashanah Foods
In the UK, as in Jewish communities worldwide, Rosh Hashanah is celebrated with symbolic foods. The holiday meal often includes apples dipped in honey, which represent the hope for a sweet new year. Other traditional dishes include challah bread, pomegranates (symbolizing abundance), and fish heads (symbolizing leadership and prosperity).
British Jews may adapt traditional Rosh Hashanah dishes to include local ingredients or flavors, blending Jewish customs with British culinary traditions. For example, roast lamb or brisket may feature prominently in holiday meals, alongside side dishes like roasted vegetables and potatoes.
Synagogue Attendance and Rituals
For many Jews in the UK, Rosh Hashanah involves attending synagogue services, where special prayers and readings are recited. The prayers emphasize themes of repentance, forgiveness, and renewal. In Orthodox and some Conservative communities, Rosh Hashanah services may be longer and more formal, while Reform and Liberal synagogues may offer shorter, more accessible services.
A central part of Rosh Hashanah observance is the Tashlich ceremony, where participants symbolically cast away their sins by throwing pieces of bread or other food into a flowing body of water. In the UK, Tashlich might take place at rivers, lakes, or even the sea, depending on the location of the Jewish community.
Significance of Rosh Hashanah in Jewish Life
A Time for Reflection and Repentance
Rosh Hashanah marks the beginning of the Ten Days of Repentance, also known as the Days of Awe, which culminate in Yom Kippur, the Day of Atonement. These ten days are a time for self-reflection, spiritual renewal, and seeking forgiveness from both God and fellow human beings. Jewish tradition teaches that during this period, God reviews the deeds of each person and inscribes their fate for the coming year in the Book of Life.
The themes of repentance and renewal are central to Rosh Hashanah, and the holiday provides an opportunity for individuals to evaluate their actions over the past year and make amends for any wrongs. Many people take this time to seek forgiveness from others, strengthen relationships, and set intentions for personal growth in the coming year.
Family and Community Bonds
Rosh Hashanah is also a time for family and community gatherings. Many British Jews will come together with loved ones to share meals, exchange blessings, and reflect on the significance of the holiday. In the UK, as in other parts of the world, Jewish families may host large holiday gatherings or participate in community events organized by local synagogues.

Conclusion
While Rosh Hashanah does not fall on the same day of the Gregorian calendar each year, it always occurs on the first and second days of Tishrei in the Jewish calendar. The variation in its date on the Gregorian calendar is due to the lunisolar nature of the Jewish calendar and the inclusion of a leap month in some years. For Jews in the UK and around the world, Rosh Hashanah is a time for spiritual reflection, family gatherings, and community celebration. Whether observing the holiday with traditional foods, attending synagogue services, or participating in the Tashlich ceremony, Rosh Hashanah serves as a meaningful opportunity for renewal and the hope for a sweet new year.
