March 20 – June 21, 2025
At the spring (or vernal) equinox, days and nights are approximately twelve hours long, with daytime length increasing and nighttime length decreasing as the season progresses until the Summer Solstice in June (Northern Hemisphere) and December (Southern Hemisphere).
On average, spring lasts for 92.8 days in the Northern Hemisphere and 89.8 days in the Southern Hemisphere.
Spring’s warmer weather and increased daylight hours make it the best season. Taking walks and seeing flowers in bloom are also part of what makes spring so great.
Why is it called spring? It was not until the 1300s that the term lent was replaced by springing time, since it was the time of year when most plants that had been dormant over the fall and winter finally began to grow again, or spring from the earth.
The Spring Equinox officially marks the beginning of spring in the Northern Hemisphere, and there are celebrations around the world to usher in longer days and springtime. In some cultures, this day also marks the beginning of the new year, which in Iranian culture is called Nowruz.
This year, astronomical spring began on 20 March 2024 and ended on 21 June 2024.
