What season is it in the northern hemisphere because Earth's tilt is sideways to the sun and hours of daylight and darkness are the same in both hemisperes on about March 20?

On March 20, the northern hemisphere experiences the spring equinox, marking the beginning of spring. During this time, Earth's tilt is such that the sun is directly over the equator, resulting in approximately equal hours of daylight and darkness in both hemispheres. This event signifies a transition from winter to spring in the northern hemisphere.
