How each prayer time is calculated

Every time on this page comes from the Sun's position, not from a lookup table. For the date and coordinates you enter, the calculator finds the Sun's declination and the equation of time with the NOAA solar equations, then solves for the moment the Sun reaches a given angle.

  • Fajr begins at true dawn, when the Sun is a set number of degrees below the eastern horizon: 18° for the Muslim World League, 15° for ISNA, 19.5° for the Egyptian authority.
  • Sunrise and Maghrib use the standard horizon of 0.833° below, which allows for atmospheric refraction and the Sun's radius. Tehran's method waits until the Sun is 4.5° below for Maghrib.
  • Dhuhr is solar noon, when the Sun crosses the local meridian. Many timetables add one to five minutes for caution; use the Dhuhr minutes field for that.
  • Asr starts when an object's shadow equals its noon shadow plus its own length (standard) or twice its length (Hanafi).
  • Isha uses a depression angle such as 17° or 15°, except Umm al-Qura, which sets Isha 90 minutes after Maghrib (120 minutes in Ramadan).

Why the methods give different Fajr and Isha times

Scholars and institutions have measured the onset of dawn and the disappearance of twilight at different places, so each method uses a different angle. The difference is small at noon and large at the edges of the night. In New York on June 21, 2025, Fajr at 15° (ISNA) is about 25 minutes later than Fajr at 18° (Muslim World League), and the gap widens in summer and at higher latitudes.

The comparison table runs all six methods for your date so you can match the method your mosque uses. North American mosques commonly follow ISNA or a moonsighting-based schedule, most of Europe and East Asia use the Muslim World League, Egypt and much of Africa use the Egyptian angles, the Arabian Peninsula uses Umm al-Qura, and South Asia uses Karachi.

Summer nights at high latitudes

North of about 48.5°, the Sun may never sink 18° below the horizon on summer nights. In London on June 21 the Sun reaches only about 15° below, so an 18° Fajr and a 17° Isha do not exist astronomically. Without an adjustment a calculator would show a blank or an impossible time.

  • Angle-based: Fajr is no earlier than sunrise minus (angle ÷ 60) of the night, and Isha no later than sunset plus the same portion. For 18° that is 18/60, or 30% of the night.
  • Middle of the night: Fajr and Isha are limited to half of the night.
  • One-seventh of the night: the last seventh of the night is used for Fajr and the first seventh for Isha.

Times changed by a rule are marked on the result cards and with an asterisk in the comparison table. Near the poles, where the Sun does not rise or set at all, the calculator says so instead of inventing times.

Getting times that match your local mosque

Start by choosing the calculation method and Asr school your community follows, then compare a few days with the printed timetable. If Dhuhr is consistently two minutes later, enter 2 in the Dhuhr minutes field.

  • Coordinates matter. Moving about 110 km east or west shifts every time by roughly 4 minutes. Use the Use my location button or exact coordinates rather than a nearby big city.
  • Time zone and daylight saving time are applied through your device's time zone database for the date you pick, so a timetable for March or November already reflects the clock change.
  • Elevation and horizon are not modelled. Mountains or tall buildings can hide the real sunrise and sunset by several minutes.
  • Safety margins: many published timetables add a few minutes to Maghrib or subtract a few from Fajr. Follow your mosque when its times differ.

Frequently Asked Questions

Common questions about the Islamic Prayer Times Calculator

Use the method your local mosque or Islamic center follows. As a rule of thumb, ISNA is common in North America, the Muslim World League in Europe and East Asia, the Egyptian General Authority in Africa and the Levant, Umm al-Qura in Saudi Arabia and the Gulf, Karachi in South Asia and the Tehran method in Iran. The comparison table shows all six for your date.
