Traditionally, we 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, spring fell on March 19th, the earliest first day of spring in 124 years!
Regardless of what the weather is doing outside, the spring equinox marks the official start of the spring season.
