In weeks, months and sleeps
Weeks and months are counted from today in New York time, the same way as the day count. "Sleeps" is the number of nights before the first day of summer, which is the same as the days if you count tonight.
About this countdown
This page counts down to 21 June, the June solstice and the start of astronomical summer in the northern hemisphere. School holidays and meteorological summer start earlier; the countdown maker lets you count to whichever matters to you.
- Meteorological summer starts on 1 June; astronomical summer on the solstice, 20 or 21 June depending on the year.
- In the southern hemisphere the same date is the winter solstice — the shortest day of the year.
- US school years mostly end between late May and mid-June, so "days until summer break" is usually shorter than this count.
Questions people ask
How many days until summer break?
That depends on your school district. The school countdown page lets you put in your own last day for an exact count.
Why 21 June and not 1 June?
Both are used. 1 June is the meteorological start; 21 June is the astronomical one. This page uses the solstice because it is the same everywhere in the northern hemisphere.
