Iftar time in Singkawang is based on the astronomical sunset at 0.9°N, 109.0°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 Singkawang lasts 12h 6m, 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 0.9°N and 2m elevation in the Jakarta timezone, Singkawang 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 Pontianak at -0.0°N, this results in about 4 minutes of difference. These gradual daily changes are a defining feature of fasting in Singkawang.
Singkawang's sunset is approximately 11 minutes earlier than Pangkalpinang, primarily due to longitude differences between the cities.
Singkawang's sunset is approximately 18 minutes earlier than Tanjungpinang, primarily due to longitude differences between the cities.
Singkawang's sunset is approximately 20 minutes earlier than Batam Centre, primarily due to longitude differences between the cities.
In Singkawang, sunset shifts slightly. Specifically, today's sunset occurs 1m earlier than yesterday.
Tomorrow's fast will be approximately 1 minute longer than today in Singkawang, following the seasonal daylight pattern at 0.9° latitude. This daily progression is characteristic of Singkawang'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 2m above sea level, Singkawang'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 Singkawang's exact location (0.90°N, 108.98°E), timezone (Asia/Jakarta), and the current season to determine accurate sunset times throughout Ramadan.
Iftar in Singkawang today is the astronomical sunset time shown at the top of this page. Check the precise time, which is calculated for Singkawang's exact location (0.90°N, 108.98°E) at 2m elevation. The calculation uses the Umm al-Qura 18.5° method, which is followed across SE Asia.
Sehri end time in Singkawang 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 Singkawang'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 0.9°, Singkawang experiences relatively consistent fasting hours year-round, with minimal seasonal variation compared to other latitudes. Fasting hours in Singkawang vary daily throughout Ramadan as sunset and Fajr shift with the season. The times shown on this page are calculated for Singkawang's exact location so you can plan your fast accordingly.
Compared to Pontianak, Singkawang has sunset 1 minute earlier than Pontianak due to its more westerly position, and being further north means it has longer fasting days during Ramadan. The primary cause is the longitude difference between the cities — roughly 4 minutes of time difference per degree of longitude. Singkawang is at latitude 0.90°, while Pontianak is at latitude -0.02°. 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 Singkawang. 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.
