Spring typically ends around June 20th or 21st in the Northern Hemisphere. This date marks the summer solstice, which is the longest day of the year. After this date, the days start to get shorter, and we transition into summer.
In the Southern Hemisphere, spring ends around December 21st or 22nd, which is the summer solstice for that part of the world. This is when the days start to get shorter, and summer begins.
The exact date can vary slightly each year due to the Earth’s orbit and the way we calculate the seasons. However, June 20th or 21st is generally when spring ends in the Northern Hemisphere, and December 21st or 22nd is when it ends in the Southern Hemisphere.
