Ramadan timetable 2027 in Nusantara: calculated times
In Nusantara, the Ramadan timetable 2027 consists of two times to know each day: imsak, when the pre-dawn meal must end, and iftar, when the fast is broken at sunset. On Monday 8 February, the expected first day, imsak falls at 05:01 and iftar at 18:32.
Ramadan 2027 in Nusantara, Indonesia’s new capital in East Kalimantan, is expected from Monday 8 February. Sahur ends at the imsak time of 05:01 and buka puasa comes at 18:32, for a first fast of 13 h 30 min.

Fasting on the equator in Borneo
Nusantara lies just under one degree south of the equator, so the length of the day barely changes from one season to the next. The table above shows fasts of 13 h 30 min, 13 h 28 min and 13 h 26 min.
Unusually, the fast here becomes slightly shorter as the month advances. In the southern hemisphere, days gradually shorten after the December solstice, so the 29th fast in Nusantara is four minutes shorter than the first.
Sahur and iftar on 8 February
On the opening day, imsak is at 05:01, subuh, the dawn prayer, at 05:11 and sunrise at 06:23. Maghrib, the signal for buka puasa, comes at 18:32, and isha at 19:39, followed by tarawih in the mosques.
Imsak in Indonesia is traditionally announced ten minutes before subuh, often by sirens, drums or mosque loudspeakers across the city. This margin helps everyone finish sahur in time, while the fast itself formally begins at the dawn call.
Central Indonesia Time and the clock
Nusantara follows Central Indonesia Time, known as WITA, eight hours ahead of Greenwich. Jakarta lies in Western Indonesia Time, one hour behind, which is why clock times in the new capital differ from those in Java.
Within WITA, Makassar breaks its first fast at 18:25, seven minutes before Nusantara. On the Jakarta clock, buka puasa there is at 18:17, but it actually occurs about three quarters of an hour after Nusantara’s sunset.
Dates of Ramadan 1448 in Indonesia
The Ministry of Religious Affairs holds the sidang isbat, its official moon-sighting meeting, on the evening of 29 Shaban. Ramadan 2027 is expected to begin on Monday 8 February, with tarawih from Sunday evening 7 February.
Muhammadiyah, which relies on astronomical calculation, usually publishes its dates in advance and occasionally differs by a day. The 27th night is expected on Friday evening 5 March, and Idul Fitri on Tuesday 9 March, or Wednesday 10 March.
A note on calculation methods
This page uses the Muslim World League method, with fajr at 18 degrees and isha at 17 degrees. Official Indonesian schedules use a deeper fajr angle of about 20 degrees, so local imsak and subuh times appear several minutes earlier.
Rainforest climate and life in the new capital
February and March bring heavy tropical showers and warm, humid days around thirty degrees in East Kalimantan. Fasting in this climate requires steady hydration between buka puasa and sahur, especially for construction workers employed on the capital’s building sites.
Much of the population living near Nusantara has arrived recently from other islands, so buka puasa mixes regional traditions. Takjil such as kolak, sweet drinks and fried snacks are shared before dinner, and many offices organise buka bersama.
Travel and practical tips
Visitors usually reach Nusantara through Balikpapan, the nearest large city and airport. Whether you work on site, visit officially or live nearby, these tips can help you through the steady equatorial rhythm of the fast:
- Plan buka puasa around 18:30 for the whole month
- Remember the one-hour difference with Jakarta
- Keep rain gear handy for evening tarawih
- Follow the Ministry announcement after the sidang isbat
Why does the fast get shorter in Nusantara?
Nusantara lies just south of the equator, where daylight decreases slightly between February and March. The fast drops from 13 h 30 min on the first day to 13 h 26 min on the 29th, the reverse of Europe.
What time is the last buka puasa in Nusantara?
On Monday 8 March 2027, the 29th day, maghrib in Nusantara is at 18:28, four minutes earlier than on the first evening. Imsak that morning is at 05:01, exactly as on the first day of Ramadan.
