Jewish Calendar
Zmanim, the Hebrew date, and Shabbos times for your zip
Type a five-digit US zip code and the month draws with the Hebrew date in every square, the parsha, the yom tov, and the candle lighting and havdalah times. The zmanim themselves are worked out on the device from the sun's position for your latitude and longitude, and Use My Location will drive those from the browser; the holidays and parshiyos come from Hebcal and need the zip. The page carries the reminder that these times are for reference and the halacha comes from your Rov.
The month, both calendars

Candle lighting from your zip; zmanim worked out on the device.
What it does
A full daily zmanim sheet
Alos Hashachar, misheyakir, netz, latest Shema and latest Shacharis, chatzos, mincha gedolah and ketanah, plag, shkiah, tzeis, Rabbeinu Tam, and chatzos halayla — with day length and the sha'ah zmanis in minutes. Candle lighting joins the list on Erev Shabbos, havdalah on Shabbos.
GRA and MGA side by side
Latest Shema and latest Shacharis print both opinions on the same line with a legend, rather than making you pick one and hide the other.
Presets for your custom
One-tap chips for Chabad, Chabad (Chicago), Orthodox (GRA), Orthodox (MGA), Conservative, and Jerusalem, plus an advanced panel for the candle-lighting offset and the havdalah method — 42, 50, or 72 minutes, or 8.5° / 8.75° below the horizon.
Both calendars in one grid
Each square shows the civil date, the Hebrew date, the parsha or yom tov, and the candle or havdalah time; Fridays, Shabbos, and yomim tovim are shaded.
Move a day at a time
Arrows step the zmanim forward and back by a day with a Today button, and tabs switch between Daily Zmanim, Shabbos Times, Holidays, a list of zmanim lessons that open in Lessons, and a note on checking against Chabad.org.
Who it's for — Families who want candle lighting and the Hebrew date in the same app the children learn in, and rebbeim teaching a zmanim unit. No plan needed beyond a signed-in account — it carries no feature flag in the plan map.
