DeKALB — Sunday marks the yearly change in clocks with daylight saving time that will occur at 2 a.m. Sunday.

The time changes happen twice a year, once on the second Sunday of March and another the first Sunday of November. This time the clocks will  “fall back” an hour, going from 2 a.m. to 1 a.m.

The United States first instituted daylight saving time back in 1918, as a temporary measure to conserve energy during World War I. It was then brought back temporarily again in 1945, during World War II.  Finally, in 1966 the Uniform Time Act was created to make a universal daylight saving time throughout the United States.

The next daylight saving time will be on March 13, 2022, where we’ll “spring forward” an hour.
