June 21 is celebrated annually as the summer solstice in the northern hemisphere.

Solstices, which occur twice a year, signify the change of seasons and mark the year’s shortest and longest daylight hours, depending on the hemisphere.

These days are more noticeable to observers compared to equinoxes due to the significant difference in the length of day and night.

After enduring six months of arctic winter, the northern hemisphere experiences its longest day and shortest night of the year during the summer solstice, while the southern hemisphere enjoys summer in December.
