Rantauprapat Prayer Times

Prayer Times in Rantauprapat, Indonesia

Rantauprapatprayer times are calculated based on the city's precise geographic coordinates (2.1000°N, 99.8333°E) using the Kemenag calculation method — the standard followed by most mosques in Indonesia. 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 Rantauprapat'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 Rantauprapat prayer time calendar for the full month is shown below — so you can plan ahead without checking daily.

How Rantauprapat's prayer times are worked out

Rantauprapat sits 6,829 km (4,244 miles) from the Kaaba in Mecca, so the Qibla from here is 293° from true north — you face northwest to pray. Fajr and Isha depend on how far the sun drops below the horizon, and Indonesia follows the Kemenag method set by Kementerian Agama, Indonesia's Ministry of Religious Affairs: Fajr begins when the sun is 20° below the horizon, and Isha when it reaches 18°. 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 Rantauprapat. Measured with the Kemenag method, the longest daily fast here — from Fajr to Maghrib — runs about 13h 39m around June, while the shortest is roughly 13h 24m in December: a swing of 0h 15m across the year. That spread is set by Rantauprapat's latitude (2.10°N); cities nearer the equator barely vary, while far-northern ones swing by many hours.

One local quirk worth knowing: Dhuhr in Rantauprapat does not fall at 12:00. Because the city sits well west within its Asia/Jakarta time zone, the sun peaks about 29 minutes after clock noon, and Dhuhr follows the sun rather than the clock — today it is at 12:28 PM. The nearest cities we also publish times for are Tanjungbalai, Kisaran, Padangsidempuan — close enough that their times differ from Rantauprapat's by only a few minutes.
