Ramadan 2027 in Semarang, Indonesia

Sehri and Iftar in Semarang

For Semarang, the evening fast opens at local sunset, shown as 5:31 pm today. The pre-dawn cutoff is calculated separately from the Fajr setting; sunrise is not used as the start of the fast. The page uses Semarang’s coordinates (-6.97, 110.42) and the Asia/Jakarta time zone.

Sunrise-to-sunset daylight in Semarang lasts 12 hours 19 minutes today, and the solstice-to-solstice change is comparatively small at this latitude. The fasting interval is longer than this daylight figure because it begins at Fajr before sunrise.

Solar noon in Semarang is 11:22 am today, about 38 minutes before 12:00 on the local clock. That offset is one reason sunset can look unusually early or late when compared with another city that keeps the same time zone.

For comparison, sunset in Jayapura is 5:26 pm today, 125 minutes earlier than in Semarang. Travellers should therefore switch to the timetable for the place where they are actually observing the fast rather than carrying one city’s times across Indonesia.

This timetable uses the Karachi prayer calculation setting. The calculation notes explain how the site handles Fajr, Isha and unusual daylight conditions, so that general methodology is not repeated on every location page.
