Ramadan timetable 2027 in Jakarta: calculated times
In Jakarta, the Ramadan timetable 2027 consists of two markers, imsak in the morning and iftar in the evening, which frame each day of fasting. In the middle of the month, on 22 February, they are expected at 04:38 and 18:14.
Jakarta is expected to start Ramadan 2027 on Monday 8 February. On that first day, imsak falls at 04:34 and buka puasa at 18:17, giving a fast of 13 h 43 min in the Indonesian capital at the height of the rainy season.

| Day 1 – Mon 8 Feb | 04:34 | 04:44 | 05:56 | 18:17 | 19:25 | 13 h 43 |

Buka puasa times through the month
The table above shows Monday 8 February in Jakarta with imsak at 04:34, subuh at 04:44, sunrise at 05:56, maghrib at 18:17 and isha at 19:25. The first tarawih takes place the evening before, on Sunday 7 February.
As the month progresses, maghrib moves slightly earlier: 18:14 on Monday 22 February and 18:09 on Monday 8 March. The fast shortens from 13 h 43 min to 13 h 36 min and finally 13 h 30 min.
Six degrees south of the equator
Jakarta lies at about 6.2 degrees south, in the southern hemisphere, where days slowly shorten after the December solstice. This is why the fast loses thirteen minutes between the first and the last day of Ramadan 2027.
Imsak stays almost fixed, moving from 04:34 to 04:38 within two weeks and then remaining there, while sunset gradually comes earlier. Families in Jakarta can therefore keep a nearly identical sahur routine for the whole month.
Western Indonesia Time and other cities
Jakarta uses Western Indonesia Time, WIB, seven hours ahead of Greenwich. Within the same time zone, Bandung breaks its fast two minutes earlier at 18:15, Semarang at 18:03 and Surabaya at 17:54, while Medan waits until 18:39.
Official calendar and calculation angle
The Ministry of Religious Affairs publishes the imsakiyah schedules used by most mosques, with a fajr angle of about 20 degrees. This page uses the Muslim World League’s 18 degrees, so official imsak and subuh times in Jakarta come a few minutes earlier.
Sidang isbat and the 2027 dates
The start of the month is decided at the sidang isbat held by the Ministry in Jakarta, combining moon-sighting reports and calculation. For 2027, the first fast is expected on Monday 8 February, though a Tuesday start is possible.
The 27th night should begin on Friday evening 5 March, and Lebaran, Idul Fitri, is expected on Tuesday 9 March, or Wednesday 10 March if the month completes thirty days. Muhammadiyah often announces its own dates in advance.
Istiqlal, bedug and the city at maghrib
Istiqlal Mosque, the national mosque and the largest in Southeast Asia, hosts vast congregations for tarawih and for shared iftars. Across the city, the beating of the bedug drum and the adhan from countless mosques mark the moment of maghrib.
In the late afternoon, Jakartans go out for ngabuburit, browsing stalls selling takjil such as kolak, es buah, gorengan and martabak. Traffic peaks just before buka puasa, and many offices organise buka bersama for colleagues.
Rain, traffic and the mudik
February is usually one of the wettest months in Jakarta, with heavy downpours and sometimes floods in low-lying districts. Towards the end of Ramadan, millions leave the capital for mudik, the homecoming journey before Lebaran, emptying the city.
Office workers, university students and visitors spending Ramadan in the sprawling capital region can stay comfortable during the hot, humid and rainy weeks of the month by keeping in mind a few simple practical points:
- Set out early to beat the pre-maghrib traffic
- Keep an umbrella for evening tarawih
- Book mudik tickets well before early March
- Follow the official imsakiyah of your mosque
Is the fast in Jakarta longer than in Medan?
Yes. On the first day, Jakarta fasts 13 h 43 min, against 13 h 20 min in Medan, which lies north of the equator. Southern hemisphere cities in Indonesia have longer days in February than those in northern Sumatra.
When does Jakarta break its fast on the 15th day?
On Monday 22 February 2027, buka puasa in Jakarta is at 18:14, three minutes earlier than on the first evening. Imsak that morning falls at 04:38, and the fast lasts a total of 13 h 36 min.
