First Day of Spring
March 20, 2025
The first day of spring is March 20, 2024, at 5:02 a.m. EDT. For those of us in the Northern Hemisphere, this was marked by the arrival of the Vernal Equinox (otherwise known as the “First Point of Aries“).
Traditionally, we used to celebrate the first day of spring on March 21, but astronomers and calendar manufacturers alike now say that the spring season starts on March 20th, in all time zones in North America. In 2020 (a leap year), spring fell on March 19th, the earliest first day of spring in 124 years!
Regardless of what the weather is doing outside, spring equinox marks the official start of the spring season.
The vernal equinox officially happens at 9:01am
