When Does Spring Start?
The first day of spring depends on which definition you use. Astronomical spring begins at the vernal equinox, when the Sun is directly over the equator and day and night are approximately equal. In the Northern Hemisphere, this typically falls between March 19-21. Meteorological spring is fixed at March 1 and is used by climate scientists to align with temperature patterns.
Spring Equinox Dates (Northern Hemisphere)
| Year | Astronomical | Meteorological |
|---|---|---|
| 2025 | March 20 (Thu) | March 1 (Sat) |
| 2026 | March 20 (Fri) | March 1 (Sun) |
| 2027 | March 20 (Sat) | March 1 (Mon) |
| 2028 | March 19 (Sun) | March 1 (Wed) |
| 2029 | March 20 (Tue) | March 1 (Thu) |
Astronomical dates are based on calculated vernal equinox times. Meteorological spring is always March 1.
Spring Around the World
In the Southern Hemisphere (Australia, New Zealand, South America, southern Africa), spring begins in September. The September equinox marks the astronomical start of spring for these regions, while meteorological spring starts on September 1.
