About the countdown to the Spring Equinox
The exact equinox instant drifts by several hours from year to year and can occasionally fall on March 19 or March 21, so we anchor the countdown to March 20 for a clean, consistent target.
At the equinox the Sun crosses the celestial equator, which is why daylight and darkness are almost balanced across the globe. In the Southern Hemisphere this same date marks the start of autumn.
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 Spring Equinox falls in ISO week 11 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.
Around the same time
These fall within a fortnight of the Spring Equinox, which is useful if you are planning around the date rather than only checking it.
