Have you ever noticed how the Jewish New Year doesn’t fall on January 1st? Instead, it follows a rhythm all its own—woven into the cycles of the moon, history, and deep tradition. That’s why many people wonder: when is Rosh Hashanah 2025?
The Date That Marks a New Beginning
Rosh Hashanah in 2025 begins at sundown on Wednesday, October 1, 2025, and ends at nightfall on Friday, October 3, 2025. Like all Jewish holidays, it starts in the evening because the Hebrew calendar follows a lunar cycle, where each day begins at sunset, not midnight.
This two-day holiday ushers in the Jewish New Year, but it’s not just a celebration—it’s also the start of the “Days of Awe,” a ten-day period of reflection leading up to Yom Kippur, the holiest day in Judaism.
Why Rosh Hashanah Moves Around on the Calendar
Unlike Christmas or Independence Day, Rosh Hashanah doesn’t have a fixed date on the Gregorian calendar. Instead, it always falls on the first and second days of the Hebrew month of Tishrei. Because the Hebrew calendar is lunar-solar (based on both the moon’s phases and the sun’s seasonal cycle), Jewish holidays shift around each year in relation to the Western calendar.
Here’s what makes it fascinating:
-
A Hebrew calendar month can have 29 or 30 days.
-
A Jewish leap year isn’t just an extra day—it’s an entire extra month added to balance the lunar and solar cycles.
-
This adjustment keeps holidays like Passover in the spring and Rosh Hashanah in the fall.
So, while the Jewish year 5786 will begin in October 2025, in another cycle it could fall in September. It’s a cosmic dance between sun, moon, and centuries of tradition.
Traditions That Sweeten the New Year
The heart of Rosh Hashanah lies in both solemn reflection and joyful hope. Families gather, prayers are recited, and symbolic foods are shared. Some of the most recognizable traditions include:
-
Apples dipped in honey – symbolizing hopes for a sweet new year.
-
Round challah bread – its circular shape represents the endless cycle of life.
-
Pomegranate seeds – a fruit said to have 613 seeds, matching the 613 commandments in the Torah.
-
The shofar – a ram’s horn blown in synagogue, calling people to wakefulness and repentance.
These rituals bridge the spiritual with the everyday. Even the act of tasting something sweet becomes a prayer in itself.
Surprising Facts About Rosh Hashanah
Rosh Hashanah may seem familiar to some, but it’s full of surprising details:
-
It’s not mentioned by name in the Torah. The holiday is called “Yom Teruah” (Day of Shofar Blowing) in scripture. The name “Rosh Hashanah” (Head of the Year) came later in rabbinic tradition.
-
It’s both a holiday and a judgment day. Jewish tradition teaches that on Rosh Hashanah, God opens the “Book of Life” to inscribe what the coming year will hold.
-
The shofar is not a trumpet. It’s made from a ram’s horn, hollowed out and polished, and its sound is meant to stir the soul, not entertain.
-
It’s one of the few Jewish holidays celebrated for two days worldwide. Most holidays are only extended outside of Israel, but Rosh Hashanah is always two days, even in Jerusalem.
-
There’s a tradition called Tashlich. On the afternoon of Rosh Hashanah, people symbolically cast their sins into a flowing body of water by tossing in breadcrumbs or pebbles.
Each of these practices carries layers of history and meaning, connecting modern life to ancient memory.
When Is Rosh Hashanah 2025?
Mark your calendar: Rosh Hashanah 2025 will arrive with the setting sun on October 1st and conclude at nightfall on October 3rd. That means families will be lighting candles, gathering for festive meals, and attending synagogue during the early autumn season.
If you want to follow along or even join a community celebration, this timing makes it a wonderful opportunity to step into Jewish tradition during the cozy start of October.
Personal Insight
I once attended a Rosh Hashanah dinner where the host explained each food before serving it—why the challah was round, why we dipped apple slices into honey. It struck me how much storytelling and symbolism were baked right into the meal. It wasn’t just dinner; it was a shared vision of hope. That memory sticks with me whenever I think about new beginnings.
Conclusion
So, when is Rosh Hashanah 2025? It begins at sundown on Wednesday, October 1st and ends at nightfall on Friday, October 3rd. Beyond the dates, though, it’s a time of reflection, renewal, and sweetness for the year ahead.
Would you try dipping apples in honey this October as a little nod to the Jewish New Year?
