When exactly is the first day of summer?

Technically the first day of summer, or the summer solstice, begins on June 21, but it all depends on your time zone.

According to The Old Farmer's Almanac, the summer solstice will begin at 11:54 a.m., Friday, June 21 in the Eastern Time zone.

To make the seasons even more confusing, the summer solstice happening in the next few hours only applies in the Northern Hemisphere, the Almanac explained. In the Southern Hemisphere, they're going to be celebrating the winter solstice.

The solstice is based on the position of the sun when it reaches its northernmost point from the equator, not on a set date and time, the Almanac explained.
