The length of day and night will be approximately equal all over the world today, said Qatar Calendar House (QCH). It is because of Vernal Equinox phenomenon at 7:15pm on this day, it added.

This phenomenon is important as vernal equinox and all four astronomical seasons are an indicator for climatic changes. Moreover, on this day one can observe the exact positions of sunrise and sunset from all countries over eastern and western horizons.

Dr. Beshir Marzouk, Astronomer expert at QCH, said, “The length of day and night will be approximately equal in Qatar too, where the length of day will be 12hrs and 7min while night will be 11hr and 53min. The sunrise over Doha sky will be at 5:38am and sunset will be at 5:45pm.”

There are two reasons to Vernal Equinox Phenomenon and all four astronomical seasons: firstly, because of Earth’s rotation on its orbit around sun and secondly, Earth’s axis tilting over its orbit plane by 23.5 degrees. (Source)
