Daily Zmanim Worldwide

What Are Zmanim?

Zmanim (זמנים, "times") are the halachic times that govern daily Jewish life — the precise moments when prayers may be recited and certain mitzvot performed. Because these times depend on the sun's position relative to the local horizon, they vary by location and by season, and must be calculated for each specific latitude, longitude, and elevation.

The Key Zmanim

• Alot HaShachar (עלות השחר, "dawn"): When the first light appears; 72 minutes before sunrise.
• Misheyakir (משיכיר): The earliest time to put on tzitzit and tefillin; 10.2° below the horizon.
• Netz Hachama (sunrise): The upper edge of the sun appears over the horizon.
• Sof Zman K'riat Shema: The latest time to recite the morning Shema; one-third into daylight (GRA opinion).
• Sof Zman Tefillah: The latest time for the morning Amidah; one-quarter into daylight.
• Chatzos (חצות, "midday"): The midpoint between sunrise and sunset.
• Mincha Gedola: The earliest time for the afternoon prayer; half a seasonal hour after Chatzos.
• Mincha Ketana: Two and a half seasonal hours before sunset.
• Plag HaMincha: One and a quarter seasonal hours before sunset; the earliest time to light Shabbat candles in some opinions.
• Shkiah (sunset): The upper edge of the sun disappears below the horizon.
• Tzait HaKochavim (צאת הכוכבים, "nightfall"): When three medium stars are visible; the end of Shabbat and fasts.
