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.

Simi Valley's Elevation

At 265m above sea level, Simi Valley'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.
