Because the Earth's axis is tilted, the astronomical start of spring is determined by the sun's position. On the equinox, the sun passes directly over the Earth's equator, resulting in nearly equal hours of daylight and darkness.

Climatologists and utility companies got tired of the equinox’s sloppiness. For the sake of consistent record-keeping, they simply declared spring as March 1 to May 31. Why? Because annual temperature cycles are more predictable when you group full months. This system allows us to compare “spring 2024” to “spring 1884” without the equinox moving around. It’s less romantic, but if you work in agriculture, energy, or insurance, this is your spring.
