MWL Method
Uses the Muslim World League standard (18° astronomical twilight), widely accepted globally.
Iftar time in Lahti is based on the astronomical sunset at 61.0°N, 25.6°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 Lahti lasts 11h 10m, which is approximately 240 minutes longer than at the start of Ramadan. Fasting hours are increasing rapidly as daylight extends at your high northern latitude.
At 61.0°N and 105m elevation in the Helsinki timezone, Lahti is in the temperate zone, where seasonal daylight changes are noticeable. During Ramadan in spring, fasting hours increase by about 12 minutes each day. Your elevation adds roughly 0.4 minutes to sunset timing.
By mid-Ramadan (day 15), you'll have gained an extra 180 minutes of fasting compared to the first day. Compared to Vantaa at 60.3°N, this results in about 3 minutes of difference. These gradual daily changes are a defining feature of fasting in Lahti.
Lahti's sunset is approximately 8 minutes earlier than Tampere, primarily due to longitude differences between the cities.
Lahti's sunset is approximately 14 minutes earlier than Turku, primarily due to longitude differences between the cities.
Lahti's sunset is approximately 8 minutes later than Kuopio, primarily due to longitude differences between the cities.
In Lahti, sunset shifts slightly. Specifically, today's sunset occurs 2m later than yesterday.
Tomorrow's fast will be approximately 12 minutes longer than today in Lahti, following the seasonal daylight pattern at 61.0° latitude. This daily progression is characteristic of Lahti's extreme northern 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 105m above sea level, Lahti'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 Lahti's exact location (60.98°N, 25.65°E), timezone (Europe/Helsinki), and the current season to determine accurate sunset times throughout Ramadan.
Iftar in Lahti today is the astronomical sunset time shown at the top of this page. Check the precise time, which is calculated for Lahti's exact location (60.98°N, 25.65°E) at 105m elevation. The calculation uses the MWL 18° method, which is international default standard.
Sehri end time in Lahti 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 Lahti's exact coordinates using the MWL 18° method, though you can compare other calculation standards on this page.
Due to Lahti's high latitude of 61.0°N, Ramadan will see extreme variations in fasting duration — expect fasts ranging from under 9 hours in winter to over 18 hours in summer. Fasting hours in Lahti vary daily throughout Ramadan as sunset and Fajr shift with the season. The times shown on this page are calculated for Lahti's exact location so you can plan your fast accordingly.
Compared to Vantaa, Lahti has sunset 2 minutes later than Vantaa due to its more easterly position, and 85m higher elevation creates a slightly later sunset, 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. Lahti is at latitude 60.98°, while Vantaa is at latitude 60.29°. Even small differences in latitude and elevation create measurable shifts in when sunset occurs.
The MWL 18° method is most commonly used by mosques in Lahti. However, the best method for you depends on your local mosque or Islamic authority. We provide multiple standards on this page: MWL 18°, 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.
