When is Summer?
Astronomical summer in the Northern Hemisphere begins at the June solstice, the moment the Sun reaches its northernmost point. The exact date drifts between June 20 and June 21 from year to year, which is why this countdown computes the solstice with an astronomical algorithm instead of assuming a fixed date.
If you think of summer as starting on June 1 (the meteorological definition used by forecasters), that date is fixed — but the solstice is the astronomical first day, and it is the one most people mean by "the first day of summer."
