Frequently asked questions
How many days until summer 2027?
There are 271 days until summer on Monday, June 21, 2027. The countdown above shows the exact days, hours, minutes and seconds, and updates live in your time zone.
When is the first day of summer 2027?
The first day of summer 2027 is Monday, June 21, 2027: the June solstice arrives at 10:10 AM EDT, which is June 21, 14:10 UTC.
Does the season start at the same moment everywhere?
Yes. An equinox or solstice is a single instant for the whole planet, so the countdown reaches zero at the same moment for everyone. The date and time it shows are in your own time zone, which is why the first day of a season can be a day apart in the Americas and in Asia.
What is the difference between astronomical and meteorological summer?
Astronomical summer starts at the June solstice, which moves by a few hours each year. Meteorologists use whole months instead: meteorological summer runs from June 1 to August 31, which keeps seasonal weather records comparable.
Is this a countdown to summer vacation?
No — this counts down to astronomical summer. School summer breaks are set locally and differ from district to district, so make a countdown to your own last day of school with the countdown maker further down the page and share it with your class.
