How accurate are these Rosh Hashanah dates?

The dates come from published Hebrew-calendar conversions for 1 Tishrei, which are fixed by calculation and not subject to moon-sighting uncertainty like some other lunar-calendar holidays. They are accurate for civil calendar planning.

Does Rosh Hashanah really begin at sundown?

Yes. The Hebrew calendar day begins at sundown the evening before. The date shown in this tool is the civil calendar date on whose evening the holiday begins, not the first full daylight day that follows.

Why does Rosh Hashanah fall on a different date every year?

Rosh Hashanah starts on 1 Tishrei in the Hebrew lunar calendar, which runs about 11 days shorter than the Gregorian year. A leap month added roughly every three years occasionally pushes the date later instead of earlier.

How long does Rosh Hashanah last?

Rosh Hashanah is observed for two days, from 1 through 2 Tishrei. The countdown here targets the start of the first day, when the holiday begins at sundown.

What time zone does the countdown use?

The countdown uses your device's local date and time, so the days, hours, and minutes shown reflect your own time zone automatically.

Are dates available beyond 2031?

This tool currently covers 2025 through 2031. Dates further out will be added as they are confirmed.
