Iftar time in Gunungsitoli is based on the astronomical sunset at 1.3°N, 97.6°E. This timing already accounts for atmospheric refraction, marking the moment the sun appears to dip below the horizon.
Local Confirmation: While our Iftar times are accurate, we recommend checking with your local mosque for any community-specific adjustments or moon sighting variations.
Today's fast in Gunungsitoli lasts 12h 5m, which is approximately 20 minutes longer than at the start of Ramadan. Fasting hours are remaining stable, as equatorial regions have consistent day length.
At 1.3°N and 12m elevation in the Jakarta timezone, Gunungsitoli is in the temperate zone, where seasonal daylight changes are noticeable. During Ramadan in spring, fasting hours increase by about 1 minutes each day. Your elevation adds roughly 0.0 minutes to sunset timing.
By mid-Ramadan (day 15), you'll have gained an extra 15 minutes of fasting compared to the first day. Compared to Padangsidempuan at 1.4°N, this results in about 0 minutes of difference. These gradual daily changes are a defining feature of fasting in Gunungsitoli.
Gunungsitoli's sunset is approximately 5 minutes later than Tanjung Morawa, primarily due to longitude differences between the cities.
Gunungsitoli's sunset is approximately 4 minutes later than Medan, primarily due to longitude differences between the cities.
Gunungsitoli's sunset is approximately 6 minutes later than Tebingtinggi, primarily due to longitude differences between the cities.
In Gunungsitoli, sunset remains virtually unchanged. Specifically, today's sunset occurs 0m at the exact same time as yesterday.
Tomorrow's fast will be approximately 1 minute longer than today in Gunungsitoli, following the seasonal daylight pattern at 1.3° latitude. This daily progression is characteristic of Gunungsitoli's equatorial latitude position, where seasonal astronomical shifts directly affect fasting duration throughout Ramadan.
Earth's atmosphere bends light, causing the sun to appear slightly higher on the horizon than its actual position. This atmospheric refraction effect is already accounted for in our calculations, giving you the precise moment when the sun appears to cross below the horizon.
At 12m above sea level, Gunungsitoli's elevation affects when sunset occurs. Higher elevations see the sunset slightly later than lower areas. This elevation adjustment is included in all our calculations.
Iftar times are calculated using precise astronomical algorithms from NOAA, based on Gunungsitoli's exact location (1.28°N, 97.62°E), timezone (Asia/Jakarta), and the current season to determine accurate sunset times throughout Ramadan.
Iftar in Gunungsitoli today is the astronomical sunset time shown at the top of this page. Check the precise time, which is calculated for Gunungsitoli's exact location (1.28°N, 97.62°E) at 12m elevation. The calculation uses the Umm al-Qura 18.5° method, which is followed across SE Asia.
Sehri end time in Gunungsitoli marks when the fast begins in the morning. During Ramadan, this time shifts daily as sunrise moves earlier or later. The time shown on this page is calculated for Gunungsitoli's exact coordinates using the Umm al-Qura 18.5° method, though you can compare other calculation standards on this page.
Being near the equator at 1.3°, Gunungsitoli experiences relatively consistent fasting hours year-round, with minimal seasonal variation compared to other latitudes. Fasting hours in Gunungsitoli vary daily throughout Ramadan as sunset and Fajr shift with the season. The times shown on this page are calculated for Gunungsitoli's exact location so you can plan your fast accordingly.
Compared to Padangsidempuan, Gunungsitoli has sunset 7 minutes earlier than Padangsidempuan due to its more westerly position, and 295m lower elevation results in a slightly earlier sunset. The primary cause is the longitude difference between the cities — roughly 4 minutes of time difference per degree of longitude. Gunungsitoli is at latitude 1.28°, while Padangsidempuan is at latitude 1.38°. Even small differences in latitude and elevation create measurable shifts in when sunset occurs.
The Umm al-Qura 18.5° method is most commonly used by mosques in Gunungsitoli. However, the best method for you depends on your local mosque or Islamic authority. We provide multiple standards on this page: Umm al-Qura 18.5°, ISNA 15°, Umm al-Qura 18.5°, and Diyanet 20°. Check with your mosque to confirm which they recommend, then use that method from the options available above.
