Makkah: The Sun aligned exactly over the Holy Kaaba at 2:18 p.m. on Tuesday, 28th May. It is the time when the correct direction of Qibla can be determined.
The direction of the Qibla can be determined by monitoring the shadow of a piece of wood or plastic fixed vertically on the ground. The direction of Qibla will be opposite to the direction of the shadow.
Such astrological events occur on 28th May and 16th July every year. On these dates, the Sun aligns exactly over the Kabah.
