The Hebrew calendar is the biblical calendar used throughout scripture. It is a lunisolar calendar — months follow the moon cycle, while the year is tied to the solar cycle. God established it in Genesis 1 and formalized its structure throughout the Torah.

Yes. After the first launch, all calendar content works without an internet connection. No account or sign-in is required.
Your approximate location is used to calculate local sunset time, so the Hebrew day rolls over at the correct moment for where you are. Your location is used only on your device and is never transmitted or stored anywhere.
Red markers indicate major biblical feast days (Pesach, Shavuot, Yom Teruah, Yom Kippur, Sukkot, etc.). Green markers indicate minor observances. Gold markers indicate Rosh Chodesh — the new month.
Time Machine lets you navigate to any date — past or future — to see what the Hebrew calendar shows for that day. Tap the Time Machine button on the Today screen to use it.
