This is a phenomenon as many believe that the sun is directly overhead the equator. This has various effects on earth like having the same length of days and nights, temperature changes to higher degrees than usual before and after equinox which we are surely witnessing, people at the equator line don’t have a shadow at 12:00pm since the sun is directly above the equator.
Other effects include the full moon which helps in predicting the start and end of holy months of fasting i.e. the month of Ramadhan and lent period respectively.
We are now expecting the rains as we close March.
