Rustaq Prayer Times

Prayer Times in Rustaq, Oman

Rustaqprayer times are calculated based on the city's precise geographic coordinates (23.3908°N, 57.4244°E) using the Umm al-Qura calculation method — the standard followed by most mosques in Oman. Times shown are for today's date and update automatically at midnight.

The five daily prayers — Fajr, Dhuhr, Asr, Maghrib, and Isha — are calculated from the sun's position relative to Rustaq's latitude and longitude. As the sun's declination changes throughout the year, prayer times shift by several minutes each day. This is why a Rustaq prayer time calendar for the full month is shown below — so you can plan ahead without checking daily.

How Rustaq's prayer times are worked out

Rustaq sits 1,821 km (1,132 miles) from the Kaaba in Mecca, so the Qibla from here is 267° from true north — you face west to pray. Fajr and Isha depend on how far the sun drops below the horizon, and Oman follows the Umm al-Qura method set by Umm al-Qura University, Makkah: Fajr begins when the sun is 18.5° below the horizon, and Isha is fixed at 90 minutes after Maghrib rather than an angle. A city that used ISNA's 15° instead would get a noticeably different Fajr — which is why the method, not just the coordinates, decides the answer.

Day length is what really moves the timetable in Rustaq. Measured with the Umm al-Qura method, the longest daily fast here — from Fajr to Maghrib — runs about 15h 04m around June, while the shortest is roughly 12h 04m in December: a swing of 3h 00m across the year. That spread is set by Rustaq's latitude (23.39°N); cities nearer the equator barely vary, while far-northern ones swing by many hours.

One local quirk worth knowing: Dhuhr in Rustaq does not fall at 12:00. Because the city sits well west within its Asia/Muscat time zone, the sun peaks about 18 minutes after clock noon, and Dhuhr follows the sun rather than the clock — today it is at 12:16 PM. The nearest cities we also publish times for are Bahlā’, As Suwayq, Nizwá — close enough that their times differ from Rustaq's by only a few minutes.
