Spring Equinox 2025. The first day of spring is march 20, 2024, at 5:02 a.m. In 2025, that period falls on the night of august 12 to the morning of august 13—but unfortunately, the peak will occur just days after a full moon this time around, meaning that.

The spring equinox in the northern hemisphere will fall on march 19 at approximately 10:06 p.m., according to nasa. The vernal (spring) equinox is when the sun crosses the earth’s equator, making day and night equal.
