How it works
Schools end on different days, so set your own date. The default is June 20, close to the June solstice, the astronomical first day of summer in the Northern Hemisphere (June 20 or 21).
Worked example
If the last day of school is June 18, 2027, then on October 21, 2026 summer is 240 days away: 34 weeks and 2 days.
