NRIAG: Fall to Being September 22, Last 89 Days

The National Research Institute of Astronomy and Geophysics (NRIAG) revealed that summer officially began on Saturday, June 21.

It lasts for 92 days, 39 hours, and 37 minutes.

In the same context, NRIAG added that fall will start on Monday, September 22, and will stretch over 89 days, 20 hours, and 44 minutes. 

While winter is expected to begin on Sunday, December 21, lasting 88 days, 23 hours, and 41 minutes.

The summer solstice occurs when the sun appears at its northernmost point in the sky, aligning with Earth's position in orbit where the North Pole is tilted about 23.5 degrees toward the sun. 

This results in the longest day and shortest night of the year in the Northern Hemisphere, as sunlight hits the region at its most direct angle.

In contrast, the Southern Hemisphere experiences its shortest day and longest night at the same time.

The date of the summer solstice varies between June 20 and 22. This variation stems from the difference between the Gregorian calendar year (365 days) and the solar year (about 365.2422 days), the time it takes Earth to orbit the sun once.
