How Are These Times Calculated?

Iftar time in Coimbra is based on the astronomical sunset at 40.2°N, 8.4°W. This timing already accounts for atmospheric refraction, marking the moment the sun appears to dip below the horizon.

Sunset Calculation: Times are generated using precise astronomical calculations based on Coimbra's latitude, longitude, elevation, and timezone.
Optional Buffers: Communities can apply +3, +5, or +15 minute safety margins if desired, though these are for personal or local preference rather than necessity.

Local Confirmation: While our Iftar times are accurate, we recommend checking with your local mosque for any community-specific adjustments or moon sighting variations.

Latitude

At 40.2°N and 33m elevation in the Lisbon timezone, Coimbra is in the temperate zone, where seasonal daylight changes are noticeable. During Ramadan in spring, fasting hours increase by about 5 minutes each day. Your elevation adds roughly 0.1 minutes to sunset timing.

By mid-Ramadan (day 15), you'll have gained an extra 75 minutes of fasting compared to the first day. Compared to Leiria at 39.7°N, this results in about 2 minutes of difference. These gradual daily changes are a defining feature of fasting in Coimbra.

How Iftar Times Work

Atmospheric Refraction

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.

Coimbra's Elevation

At 33m above sea level, Coimbra'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.

Astronomical Calculations

Iftar times are calculated using precise astronomical algorithms from NOAA, based on Coimbra's exact location (40.21°N, 8.43°W), timezone (Europe/Lisbon), and the current season to determine accurate sunset times throughout Ramadan.

What is the Iftar time in Coimbra today?

Iftar in Coimbra today is the astronomical sunset time shown at the top of this page. Check the precise time, which is calculated for Coimbra's exact location (40.21°N, 8.43°W) at 33m elevation. The calculation uses the MWL 18° method, which is widely followed in Europe.

When does Sehri end in Coimbra?

Sehri end time in Coimbra 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 Coimbra's exact coordinates using the MWL 18° method, though you can compare other calculation standards on this page.

How long is the fast in Coimbra during Ramadan 2026?

At 40.2°N, Coimbra experiences moderate seasonal variation in daylight, affecting fasting duration throughout Ramadan. Fasting hours in Coimbra vary daily throughout Ramadan as sunset and Fajr shift with the season. The times shown on this page are calculated for Coimbra's exact location so you can plan your fast accordingly.

Why does Iftar in Coimbra differ from Leiria?

Compared to Leiria, Coimbra has sunset 2 minutes later than Leiria due to its more easterly position. The primary cause is the longitude difference between the cities — roughly 4 minutes of time difference per degree of longitude. Coimbra is at latitude 40.21°, while Leiria is at latitude 39.74°. Even small differences in latitude and elevation create measurable shifts in when sunset occurs.

Which calculation method should I use for Iftar in Coimbra?

The MWL 18° method is most commonly used by mosques in Coimbra. 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°.
