Depending on the floor they are living on, UAE residents of the famous Burj Khalifa and other tall towers have been advised to adjust their Iftar timings. During Ramadan, daytime fasting for Muslims ends at sunset. Looking from a shorter altitude at the same coordinates of the location of the 830m-tall Burj Khalifa or similar elevations, you won’t see farther along Earth’s curvature.
According to renowned astrophysicist, Neil deGrasse Tyson, “For Burj Khalifa, the current tallest building in the world, the sun sets four minutes later at the top than at the bottom. High-floor dwellers see beyond the ground-level horizon, farther along Earth’s curvature.”
Scientifically speaking, the sun, moon, stars and all celestial bodies appear to set later the higher the altitude. This is one of the evidence that Earth is a sphere and not flat ground.
The time difference at such heights will result in Fajr prayers being held two minutes earlier than the rest of Dubai and will delay Maghrib and Isya’ prayers by another two minutes.
Residents who stay between the 60th to the 120th floor will fast for four minutes more than others in Dubai while those who live on the 121st floor and higher will have to fast six minutes more than everyone else.
