I just found out that spring in the United States officially started recently, on March 20th at 10:46 a.m. (Eastern Time). The interesting thing is that it’s not always on the same day; it can vary between March 19th and 21st depending on the year.

That day is called the equinox, and it’s when the Sun crosses the Earth’s equator. What I found curious is that during that moment, day and night are almost the same length. After that, the hours of daylight start gradually increasing until June, when summer arrives.

By the way, there are two ways to measure when spring begins: the astronomical (based on Earth’s orbit), which is the equinox, and the meteorological one, which simply starts on March 1st. Some still use Groundhog Day on February 2nd as a reference, although that’s more of a tradition than an exact science.

This season will last about 92 days in 2026, until June 20th or 21st. Depending on the state you live in, temperatures can rise quickly or there may still be cold fronts. Strange how this works, isn’t it?
