How many days until summer 2027?
A live countdown to 1 June 2027, the start of meteorological summer in the Northern Hemisphere — a Tuesday. This page names a year on purpose, and handles the aftermath honestly.
Live countdown
What this page counts to, and why it names a year
The target is 1 June 2027, the first day of meteorological summer in the Northern Hemisphere, which falls on a Tuesday. Meteorological seasons run in whole calendar months — summer is 1 June to 31 August — which is the convention used by national weather services because it makes year-on-year climate comparisons clean. The alternative, astronomical summer, begins at the June solstice on the 20th or 21st; the evergreen summer page covers that distinction in full.
Most pages on this site refuse to name a year, because a countdown tied to one date is wrong forever afterwards. This one is a deliberate exception for people searching for a specific summer. It is built with the expiry in mind: while 1 June 2027 is ahead, you get a live clock; once it has passed, the page says so, tells you how long ago it was, and sends you to the evergreen countdown rather than displaying a negative number or a frozen figure.
Planning around summer 2027
Meteorological summer 2027 runs from Tuesday 1 June to Tuesday 31 August, which is 92 days including both ends. Astronomical summer begins around 21 June and ends at the September equinox, giving a slightly different window that starts about three weeks later. If you are working out school terms, a summer let, a project window or a seasonal contract, the date difference calculator will tell you exactly how many days and working days any range contains — and will show you both the inclusive and exclusive totals, which is where seasonal date ranges most often go wrong.
2027 is not a leap year, so February has 28 days and every date falls one weekday later than it did in 2026.
