Countdown to Summer
About this countdown
This countdown points to June 21, the traditional first day of summer in the Northern Hemisphere — the longest, sunniest stretch of the year. Bright yellows, warm type, and a timer that updates every second in your local time zone.
Students and teachers: the work days remaining counter reads just as well as “school days remaining.” Counting those down is a tradition for a reason.

The first day of summer marks the June solstice — the moment Earth's northern half tilts most directly toward the sun, delivering the longest daylight of the year. Cultures have marked it for millennia: Stonehenge aligns with the solstice sunrise, and midsummer bonfires and festivals remain major holidays across Scandinavia and the Baltics.
There are actually two “first days of summer.” Meteorologists start summer on June 1, using clean three-month blocks for record-keeping, while the astronomical season begins at the solstice around June 20–21. This countdown uses June 21, the date most people mean when they count down to summer.
Summer: Facts Worth Knowing
- On the June solstice, areas above the Arctic Circle get 24 hours of continuous daylight — the midnight sun.
- The word solstice comes from Latin sol (sun) and sistere (to stand still), because the sun's path pauses before reversing.
- In Sweden and Finland, Midsummer is one of the biggest holidays of the year, rivaling Christmas.
- Despite the longest day, the hottest weeks usually come later in July — oceans and land take time to heat up, an effect called seasonal lag.
- The Northern Hemisphere's summer solstice is the Southern Hemisphere's winter solstice — seasons flipped.
- For students, the real countdown is the last day of school — create a personalized one on the Make Your Own page and watch the school days tick away.
