Shabbat and Yom Tov, on one calendar
ShabbatRise knows the Jewish year and works it out on your phone, with no internet involved. An alarm you set once returns on every day you put the phone down, and stops by itself every time.
See how it works
One occasion, not four separate days
Consecutive rest days join into a single occasion. Rosh Hashanah is one block on the calendar rather than two entries you set separately, and a Yom Tov that runs into Shabbat is one block of three days. Each calendar day inside it is configured on its own, so a first-night alarm and a second-morning alarm are different alarms. The night the occasion ends is an ordinary night, and nothing is scheduled to ring on it.
Always, or only this day
Every alarm answers one question when you save it. Always brings it back on every Shabbat and every Yom Tov, for as long as you leave it switched on. Only this day rings once, on the date you ticked, and is then finished. A one-off alarm is deleted without a warning; a weekly one stops to tell you it will stop ringing everywhere before it goes.
One day of Yom Tov or two
This comes from the city you chose when you set the app up, and you are never asked it as a question. A city in Israel keeps one day of Yom Tov, a city anywhere else keeps two, and Rosh Hashanah is two days in both. Sukkot runs one day of Yom Tov and six of Chol HaMoed in Israel and two and five elsewhere; Pesach runs seven days or eight; in Israel Simchat Torah is Shemini Atzeret. If you travel for Yom Tov, change the city before you go, and ask your rabbi what you keep where you are going.
What the calendar draws, and what it does not
The month grid draws Shabbat, Rosh Hashanah, Yom Kippur, Sukkot, Shemini Atzeret, Simchat Torah, Pesach and Shavuot, each with its own mark, and shades Chol HaMoed as a lighter band of the same festival. A bell on a date means an alarm is set for it. Chanukah, Purim, Rosh Chodesh, the fast days and the weekly parashah are not drawn, and there is no omer count. Those are days you may use the phone, so the alarm clock already on it still works. ShabbatRise builds the days you put the phone down for.
