when is the 1st day of spring

The 1st day of spring in 2026 is Friday, March 20, marked by the spring (vernal) equinox in the Northern Hemisphere.

Quick Scoop: When Is the 1st Day of Spring?

• In 2026, spring starts on March 20 in the Northern Hemisphere.

• The equinox happens at about 10:46 a.m. Eastern Daylight Time (EDT), which is 14:46 UTC.

• Many calendars now treat March 20 as the official first day of spring across North America.

Why That Date?

• Astronomically, spring starts at the spring equinox, when Earth’s tilt makes day and night roughly equal in length.

• From that point on, days get longer and nights shorter until the summer solstice in June.

Fun Extra: Not Everywhere the Same

• In the Southern Hemisphere, that same March equinox actually marks the beginning of autumn, not spring.

• Their “first day of spring” comes around the September equinox instead.

TL;DR: The 1st day of spring (astronomical) in 2026 is March 20 in the Northern Hemisphere, at the moment of the spring equinox.
