Weeks Until First Day of Summer (Northern Hemisphere) 2027

First Day of Summer (Northern Hemisphere) 2027 falls on Monday, June 21, 2027 — a Monday. As of today that is 241 days, or 34 weeks and 3 days. The table below lists every "weeks to go" milestone between now and the date, so you can work backwards from the day itself instead of counting forward from today.

Why the week count moves the way it does

Weeks are the unit people actually plan in. Deadlines, notice periods and rotas run in weeks, which is why a week count tends to be more useful than a raw day count once you are more than a fortnight out. Note that the two figures answer slightly different questions: "how many weeks" is full weeks only, while "weeks and days" keeps the remainder.

About First Day of Summer (Northern Hemisphere) 2027

The june solstice of 2027 falls on June 21, 2027 at 14:06 UTC — the astronomical start of summer in the Northern Hemisphere (winter below the equator).

Astronomically, this is the Sun at its northernmost point — summer begins in the north, winter in the south. It is also the day the tide of daylight turns: after the June solstice the change is barely minutes per week, then accelerates — the reason the weeks after a solstice feel darker (or lighter) faster than the solstice day itself.
