Ramadan timetable 2027 in Surabaya: calculated times
In Surabaya, the Ramadan timetable 2027 consists of the imsak time, the limit for the last meal before dawn, and the iftar time, the moment the fast is broken at sunset. The fast lasts 13 h 45 on the first day and 13 h 31 on the twenty-ninth.
Surabaya expects the first fast of Ramadan 2027 on Monday 8 February. Sahur ends at 04:09 and buka puasa begins at 17:54, the earliest iftar among the Indonesian cities on this site, after a fast of 13 h 45 min.

East Java breaks its fast first
Surabaya lies at the eastern end of Java, more than five degrees of longitude east of Jakarta, yet both cities share Western Indonesia Time. As a result, the sun sets much earlier on the Surabaya clock, at 17:54 on the first day.
That first iftar comes 23 minutes before Jakarta at 18:17, nine minutes before Semarang at 18:03 and two minutes before nearby Malang at 17:56. Medan, in northern Sumatra, waits until 18:39, a full 45 minutes later.
Times for the 1st, 15th and 29th days
On Monday 8 February, imsak is at 04:09, subuh at 04:19, sunrise at 05:32, maghrib at 17:54 and isha at 19:02. Such an early dawn means a very early sahur, which many households begin around 03:30.
On Monday 22 February, iftar comes at 17:51 after 13 h 38 min of fasting. On Monday 8 March, the 29th day, maghrib is at 17:46, imsak at 04:14, and the fast lasts 13 h 31 min.
Southern hemisphere: shorter days
Located about 7.2 degrees south of the equator, Surabaya sees its days shorten slowly after the December solstice. The fast therefore loses fourteen minutes over the month, while dawn moves a few minutes later and sunset a few minutes earlier.
Ministry schedules and the angle used here
The times on this page come from the Muslim World League method, with 18 degrees for fajr and 17 for isha. The official imsakiyah of the Ministry of Religious Affairs uses a deeper angle for subuh, so mosque schedules show slightly earlier dawn times.
The 2027 calendar in East Java
The national sidang isbat in Jakarta will confirm the start of Ramadan 1448, expected on Monday 8 February 2027. Tarawih would begin on Sunday 7 February, while Muhammadiyah publishes its calculated dates in advance and may differ by a day.
If the forecast holds, the 27th night arrives on Friday evening 5 March and Idul Fitri on Tuesday 9 March 2027. A thirty-day month would move Lebaran to Wednesday 10 March, with mudik traffic heavy across East Java beforehand.
Ampel, Al-Akbar and the evening atmosphere
The historic Sunan Ampel Mosque, in the old Arab quarter, attracts pilgrims and worshippers throughout Ramadan, and the surrounding lanes sell dates, perfumes and Middle Eastern snacks. The large Al-Akbar National Mosque also hosts crowded tarawih prayers.
Iftar often begins with sweet takjil such as kolak and es campur, followed by East Javanese favourites such as rawon, the dark beef soup flavoured with keluak, or lontong with vegetables. Many neighbourhoods share free takjil with passers-by.
Heat, humidity and practical advice
Surabaya is hot and humid throughout the year, with frequent heavy rain in February. The combination of heat and an early dawn calls for careful planning, so workers, students and visitors should keep the following points in mind:
- Set a sahur alarm around 03:30
- Drink plenty of water between 17:54 and 04:09
- Visit the Ampel quarter in the late afternoon
- Check mosque times based on the official imsakiyah
Why does Surabaya have such an early iftar?
Surabaya lies far east within Western Indonesia Time, whose clocks are set for the whole of Java and Sumatra. The sun therefore sets earlier on the clock than in Jakarta or Medan, giving an iftar at 17:54 on 8 February.
Is the fast in Surabaya longer than in Jakarta?
Only by two minutes on the first day: 13 h 45 min in Surabaya against 13 h 43 min in Jakarta. Both cities are at similar southern latitudes, so the difference in fasting length is tiny compared with the gap in clock time.
