How many days until spring?
Live countdown to the spring equinox - the astronomical first day of spring. Auto-detects your hemisphere; toggle if needed.
How this spring countdown works
This tool counts to the spring equinox, the astronomical start of spring, when the sun crosses the celestial equator and day and night are close to equal. It guesses your hemisphere from your device’s time zone, and you can switch it with the Northern and Southern buttons. In the Northern Hemisphere spring starts at the March equinox; in the Southern Hemisphere it starts at the September equinox, the same moment as the north’s autumnal equinox.
Once the date passes, the counter moves on to the next spring equinox.
Spring dates for the next five years
| Northern Hemisphere (March equinox, UTC date) | Southern Hemisphere (September equinox, UTC date) |
|---|---|
| March 20, 2027 | September 23, 2027 |
| March 20, 2028 | September 22, 2028 |
| March 20, 2029 | September 22, 2029 |
| March 20, 2030 | September 22, 2030 |
| March 20, 2031 | September 23, 2031 |
The exact moment is given in Coordinated Universal Time. This tool counts to the start of that date at midnight in your time zone, so where you live the astronomical moment can fall a day earlier or later than the date shown.
Why the date moves
The calendar year and the time the Earth takes to orbit the sun are not quite the same length, so the equinox drifts by several hours each year and leap days pull it back. That is why it usually lands on March 20 or 21 and on September 22 or 23, depending on the year and your time zone.
Astronomical vs meteorological spring
Weather services use whole months so seasons are easier to compare: spring is March, April and May in the north and September, October and November in the south, starting on March 1 or September 1. This tool uses the astronomical equinox instead.
