About this countdown
Astronomical summer in the Northern Hemisphere starts at the June solstice, when the Sun is farthest north and the day is the longest of the year. In 2027 that happens at Monday, June 21, 2:11 PM UTC, which is Monday, June 21, 10:11 AM in New York. It is one instant everywhere, so the local date depends on your timezone. The countdown above runs to that moment in your own timezone. South of the equator the same moment is the first day of winter and the shortest day. Meteorologists count summer from June 1 instead. Before summer comes the first day of spring, and for the long weekend after it the 4th of July countdown.
