Countdown Timer for Any Date →About the Summer Solstice
At the June solstice the Sun stands directly over the Tropic of Cancer, as far north as it ever gets. For everyone in the Northern Hemisphere this is the longest day of the year, and north of the Arctic Circle the Sun does not set at all. From the next day on, daylight slowly shrinks again, even though the warmest weeks are usually still ahead because oceans and land take time to heat up.
In Australia, South America, and southern Africa the same June moment is the shortest day and the start of winter. Their summer opens at the December solstice, which is why the switch above swaps the date and the timer.
On the meteorological calendar used for weather records, summer is June, July, and August (December through February in the south).

FAQ
When does summer start?
On the astronomical calendar, northern summer starts at the June solstice: 2:11 PM UTC on Monday, June 21, 2027. Meteorologists start it earlier, on June 1, and in the Southern Hemisphere summer begins with the December solstice.
Is the summer solstice the longest day of the year?
Yes, in the hemisphere where summer is starting. In the north, the June solstice brings the most daylight of the year: about 15 hours in New York and more than 18 in Stockholm. Sunsets keep getting later for about a week afterward, so the latest sunset comes a few days after the solstice.
Is the first day of summer always June 21?
The June solstice moves between June 20 and June 22. For years to come it lands on June 20 or 21, depending on how the leap-year cycle lines up and on the time zone you read it in.
