What is First Day of Astronomical Spring?
The first day of astronomical spring marks the March equinox in the Northern Hemisphere. It is based on Earth’s position around the Sun, not a fixed civil calendar date. Around this point, daylight and nighttime are close in length, and the season shifts toward longer days.
Calendar note
Astronomical spring is different from meteorological spring. Meteorological spring starts on March 1 every year, while astronomical spring starts at the March equinox.
Date variation note
The equinox can fall on March 19, March 20, or March 21 depending on the year and time zone.
Planning note

Regional note
In the Southern Hemisphere, the March equinox marks the start of astronomical autumn, not spring.
Weather note
Spring weather does not always begin on the equinox. Local climate, altitude, ocean patterns, and latitude can make spring conditions arrive earlier or later.
