Dubai: Residents on the higher floors of Burj Khalifa, the world’s tallest tower in Dubai, should end their day’s fast a few minutes later than those at ground level, a top cleric has said.

Ahmad Al Haddad, Grand Mufti of Dubai, explained that the fast lasts until the complete setting of the sun, which is visible for a longer time at high altitudes.

According to astronomers, the sun rises earlier and sets later at higher altitudes compared to the same location at ground level.

On a plane cruising at 12,000 metres, for instance, the variation in altitude is approximately linear, meaning sunset is later by one minute for every 1.5 kilometres in altitude, and sunrise is earlier by the same amount of time.

In high-rises that have less than roughly 80 floors, the difference in timing is negligible. More info
