Astronomical start, computed with Meeus' equinox and solstice formulas (accurate to about a minute).

When does spring start?

Astronomical spring begins at the equinox, when the Sun crosses the celestial equator and day and night are roughly equal. In the Northern Hemisphere that is the March equinox (March 19–21); in the Southern Hemisphere spring starts at the September equinox (September 22–23). Meteorologists use whole months instead: spring is March 1 in the north and September 1 in the south.

Frequently asked questions

When is the first day of spring 2027?

In the Northern Hemisphere, spring 2027 begins at the March equinox: Mar 20, 20:25 UTC.

Why does the equinox date change?

A calendar year is not exactly the length of a solar year, so the equinox drifts by about six hours each year and leap days pull it back.
