Why Does Fajr Time Change in Doha?
Fajr follows the changing position of the sun below Doha's horizon before sunrise. As the Earth moves through the year, the timing of dawn, sunrise and the interval between them changes with the season. Doha's coordinates also matter because solar events occur according to a location's longitude and latitude. The movement is normally gradual, so a difference of a minute or a small number of minutes between consecutive dates is expected. Checking the current day prevents an older calendar entry from being mistaken for today's Fajr boundary.
