Longest day of the year

Karachi: Karachi has 14 hours longest day on the summer solstice that occurs every year between June 20 and June 22 in the Northern Hemisphere.

It is the longest day of sunlight for places in the Northern Hemisphere and the shortest day for cities in Southern Hemisphere, informed Dr. Javed Iqbal, Director- Institute of Space and Planetary Astrophysics (ISPA), University of Karachi, while sharing his views about the longest day.

On summer solstice, Earth's maximum axial tilt (declination) to our star, the Sun, during a solstice is 23° 27', he added.

Another interesting fact is that the distance between Earth and Sun is maximum on summer solstice which is vice verse for winter solstice (Dec 21-22) i.e. distance between Earth and Sun is minimum and so shortest day in Northern Hemisphere. (PPI)
