The Qatari Calendar House announced that the sun will be completely perpendicular to the Tropic of Cancer in the northern hemisphere on Tuesday, June 21, 2022, at 12:08 pm local time in Doha.
Dr. Marzouk added that the phenomenon of the summer solstice comes after the phenomenon of the vernal equinox that occurred last March, as the sun continued its apparent movement gradually towards the north after being perpendicular to the equator on the day of the vernal equinox, and the length of the day gradually increased over the inhabitants of the northern hemisphere.
This gradient will reach its climax with the longest day and shortest night on Tuesday, while the opposite will happen on the same day in the southern hemisphere, and they will have the shortest day and the longest night on this day.
In addition, the reason for the occurrence of the four astronomical seasons (winter, spring, summer, and autumn) is the rotation of the Earth in its orbit around the sun, in addition to the tilt of the Earth’s axis at the level of its orbit at an angle of 23.5 degrees.
The day after the summer solstice, the sun will begin its apparent movement towards the south again, as the length of the day will be shorter, while the length of the night will increase until the day and night are equal on Friday, September 23, 2022. On this day, the sun will be completely perpendicular to the equator, signaling the date of the autumnal equinox for the inhabitants of the northern hemisphere.
