How Are These Times Calculated?

Iftar time in Ruislip is based on the astronomical sunset at 51.6°N, 0.4°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 Ruislip'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.

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.

Ruislip's Elevation

At 47m above sea level, Ruislip'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 Ruislip's exact location (51.58°N, 0.43°W), timezone (Europe/London), and the current season to determine accurate sunset times throughout Ramadan.
