Zawal time is commonly used in prayer timetables for the restricted period around the sun’s midday transit. There is no single clock time or fixed number of minutes that applies to every city and date. For worship, follow a trusted local timetable and ask a qualified scholar about the ruling relevant to your prayer.
Solar noon, Zawal and Dhuhr
Solar noon is when the sun crosses the observer’s meridian. It is not necessarily 12:00 on the clock, and the sun need not be directly overhead. In religious usage, zawal refers to the sun’s decline past its midday position; the restricted interval around transit and the beginning of Dhuhr should not be treated as the same instant.
Sahih Muslim 831 describes restrictions around sunrise, the midday position until the sun has passed it, and sunset. This reference does not provide a universal five-, ten- or fifteen-minute clock interval. Details and exceptions require the guidance of the school of law you follow.
How to check the time for your location
- Choose the correct city or coordinates and the date you need.
- Check the time zone, including any daylight-saving adjustment.
- Use the published Dhuhr start and any separately marked restricted interval in a trusted local prayer timetable.
- If two timetables differ, compare their location and time-zone settings, then ask the issuing mosque or authority about its calculation and safety margin.
Our prayer times calculator can help compare calculation settings. Its output should be checked against your local timetable. A calculator does not determine religious exceptions.
Why sunrise and sunset are only a rough shortcut
The midpoint between published sunrise and sunset can be a useful approximation to midday. It should not be presented as an exact prayer boundary: rounded timetable entries and different horizon assumptions can affect that shortcut. Use an explicit solar-transit calculation or an authoritative local timetable when the distinction matters.
NOAA’s published solar equations give this approximation for transit, using longitude positive east and the equation of time in minutes:
Solar noon in UTC minutes ≈ 720 − (4 × longitude) − equation of time.
Add the local UTC offset in minutes to express the result on the local clock.
Illustrative arithmetic: With longitude 67° east, a UTC offset of +5 hours, and a hypothetical equation of time of +10 minutes, the result is 720 − 268 − 10 + 300 = 742 minutes after local midnight, or 12:22. The +10 value is an example, not today’s measured value. This is a transit estimate, not a declaration of when a prayer is permitted.
Common mistakes
- Assuming midday is always 12:00.
- Reusing yesterday’s time without checking the date.
- Treating a city-wide rounded time as exact for every surrounding location.
- Calling the sun’s highest daily position the “zenith” in the literal sense of directly overhead.
- Adding a fixed interval without knowing the local timetable’s method.
How long should I avoid praying?
This article does not prescribe a universal duration. Use the interval published by your trusted local authority. Questions about obligatory, missed, funeral or other prayers and exceptions should go to a qualified scholar; a general astronomy calculation cannot resolve them.
Correction, 1 October 2026: Replaced the claim that sunrise/sunset midpoint gives an exact Zawal time, removed a universal-duration implication, and separated solar transit from religious timing guidance.
