Countdown to Summer
Monday, June 21, 2027About the countdown to Summer
The exact solstice instant drifts by a few hours each year, so we anchor the countdown to June 21 for a clean, consistent target.
In the Southern Hemisphere this same date marks the start of winter, so the counter doubles as a seasonal marker.
The counter above reads from your device clock and refreshes every second, so the days, hours, minutes and seconds always reflect the time remaining right now. When Summer arrives, the page quietly moves its target to the following year so the countdown never runs out of road.
