Despite sleep experts -- and the president -- wanting to eliminate time changes, daylight saving time is about to begin again.

The spring equinox, also known as the vernal equinox, marks the official start of the season, which happens on Thursday, March 20, 2025.

It wasn't until the passing of the Uniform Time Act of 1966 that daylight saving became permanent, which established time zones across the country. The act stated that clocks would advance by one hour at 2 a.m. on the last Sunday in April and turn back one hour at 2 a.m. on the last Sunday of October.
