About the countdown to the Summer Solstice
The precise solstice moment shifts by a few hours each year and can land on June 20 or June 21, so the countdown anchors to June 21 to stay consistent from one year to the next.
At the June solstice the Sun reaches its highest point in the northern sky, giving the most daylight of the year. South of the equator the very same date is the shortest day and the start of winter.
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. The next the Summer Solstice falls in ISO week 25 of 2027. When the day arrives the page says so instead of showing a zero, and from the following day it moves its target to 2028, so the countdown never runs out of road.
