Worked example: counting by hand
From October 11, 2026 to Tuesday, June 1, 2027, add the days of each month:
- October 11 to November 1: 21 days
- November 1 to December 1: 30 days
- December 1 to January 1: 31 days
- January 1 to February 1: 31 days
- February 1 to March 1: 28 days
- March 1 to April 1: 31 days
- April 1 to May 1: 30 days
- May 1 to June 1: 31 days
- Total: 233 days, the same as the counter shows on that day.
When does summer start?
It depends on the definition. NOAA’s National Centers for Environmental Information says that meteorological summer includes June, July and August, so it starts on June 1. The same page says the summer solstice, the astronomical start, falls on or around June 21 in the Northern Hemisphere. We count to June 1 because it is the same date every year; the solstice moves by a day.
How many days until the summer solstice?
About three weeks after June 1. We did not find an official table of solstice times open to us today, so the exact date and time of the 2027 solstice are not confirmed here. Add 20 days to the June 1 count for a rough figure.
How many days until summer from today?
The counter calculates it. From October 11, 2026, June 1, 2027 is 233 days away, or 33 weeks and 2 days.
Questions about the date of summer
Why does this page count to June 1?
It is a fixed date, so the count does not shift from year to year, and the NOAA page we opened says meteorological summer includes June, July and August.
Does this work for the Southern Hemisphere?
No. Seasons are reversed there, and this page counts only the Northern Hemisphere date.
What weekday is June 1, 2027?
Tuesday.
When does summer end?
Meteorological summer ends on August 31, since it covers June, July and August.
