Ramadan Sehri & Iftar Time Calculator

A Ramadan Sehri & Iftar Time Calculator computes the start (Fajr) and end (Maghrib) of the daily fast for your location and date during Ramadan. Sehri is the pre-dawn meal that must end before the Fajr azan; Iftar is the meal that breaks the fast at sunset. The calculator uses the same astronomical algorithms as the major Islamic apps and supports all seven mainstream Fiqh methods.

restaurant_menu Sehri ends at Fajr

Stop eating and drinking at the start of the Fajr azan. Most scholars recommend a 5–10 minute buffer (ihtiyat) before Fajr.

wb_twilight Iftar at Maghrib

Open the fast at the call of the Maghrib azan — the moment the sun fully sets. The recommended sunnah is to break the fast immediately with dates and water.

Above ~48° N/S, true Fajr/Maghrib become extreme. The calculator uses the standard "Angle-Based" approximation in those cases — match your local masjid's timetable.

Formula & methodology

Formula: Sehri = Fajr (sun at method’s depression angle); Iftar = Maghrib (sunset); NOAA solar algorithm

  1. Enter your coordinates, UTC offset, date and calculation method.
  2. The NOAA solar algorithm computes sunset (Iftar) and the Fajr twilight crossing for the method’s angle (Sehri end).
  3. Fast duration and the Hijri date are included.

Worked example — Makkah, 10 June 2026, MWL: Sehri ends 04:13, Iftar 19:02, a fast of 14 h 49 min; the same engine matched NYC prayer times to the minute in earlier session checks.

Frequently asked questions

What time does Sehri end?
At Fajr — when the sun reaches your method’s twilight angle below the horizon (18° MWL, 15° ISNA). Enter your city and date for the exact minute; eating stops at the Fajr adhan.
What time is Iftar?
At Maghrib — actual sunset for your coordinates. The tool computes it astronomically, matching published timetables to within a minute.
Why do timetables for my city differ slightly?
Different Fajr angle conventions (15°–19.5°) shift Sehri by 20–40 minutes, and some mosques add safety buffers. Match the method your local masjid follows.
How long are fasts in Ramadan 2027?
Ramadan 1448 runs roughly 8 Feb – 9 Mar 2027. Northern-hemisphere fasts are mid-length then: ~13 hours in London, ~12.5 in New York — your exact figure comes from the date you enter.
What about extreme latitudes?
Above ~48° the 18° twilight may never end in summer; communities then follow fatwa-based rules (nearest valid city, Makkah times, or fixed intervals). The calculator returns standard astronomy where defined.
