When will the longest day of the year be observed?

The summer solstice, which marks the longest day of the year in the northern hemisphere, falls on June 21. According to the astronomical definition, the summer solstice marks the first day of summer.

Although the term is often used to refer to the longest day of the year, the astronomical phenomenon occurs at a specific time when the earth’s North Pole tilts closest to the Sun.
