夏至是白天最长的一天？英语？

The summer solstice is the day with the longest amount of daylight in the year.This is due to the Earth's axial tilt, which causes the Northern Hemisphere to be angled towards the Sun during the summer months.As a result, the Sun's rays hit the Northern Hemisphere at a more direct angle, leading to longer days and shorter nights.The summer solstice typically occurs on June 20 or 21 in the Northern Hemisphere and December 21 or 22 in the Southern Hemisphere.It is an important astronomical event that has been celebrated by various cultures throughout history.
