Counting in your browser timezone…

Summer starts at the June solstice, when the sun reaches its farthest point north and the Northern Hemisphere gets its longest day. The date is June 20 or 21, and this countdown targets that calendar date in US Eastern time before rolling to the following year. Long before the solstice, many Americans treat Memorial Day weekend as the unofficial opening and Labor Day as the unofficial close. Meteorologists start earlier still, counting June 1 as day one of the season.

FAQ

When is the first day of summer?
The astronomical first day of summer is the June solstice — next on Monday, June 21, 2027, then Tuesday, June 20, 2028. It falls on June 20 or 21 depending on the year, and the exact hour changes from one year to the next. After that date ends in your timezone, this page starts counting to the next solstice.
Is the solstice really the longest day of the year?
For the Northern Hemisphere, yes: it has the most daylight of any date, though the difference from neighboring days is only seconds. The hottest weather arrives weeks later, because land and oceans keep absorbing more heat than they release until late July or August. That delay is called seasonal lag.
Why do some calendars say summer starts June 1?
Meteorologists divide the year into three-month blocks so temperature and rainfall records line up cleanly, which puts summer at June through August. The solstice version shifts by a day between years. This page counts to the solstice, since that is the date most search results and wall calendars show.
When does summer break start?
There is no single date. US school districts finish anywhere from late May to late June and go back between early August and after Labor Day, depending on the state and district. Check your district calendar, then set a dated countdown on the any-date page for your last day of class.
Is summer the same season south of the equator?
No. The June solstice starts winter in the Southern Hemisphere, and their summer begins with the December solstice. Near the equator seasons matter less and wet and dry periods matter more. Everything on this page assumes the Northern Hemisphere and the US Eastern calendar date. If you live in Australia, Chile or South Africa, your first day of summer is the December solstice, which the winter page counts to, and this June date marks the start of your winter.
