Daylight Saving Time begins Sunday, March 12, at 2 a.m. Remember to set your clocks ahead one hour before going to bed Saturday night.

In the United States, “Fast Time” as it was called then, was first introduced in 1918 when President Woodrow Wilson signed it into law to support the war effort during World War I.

Only seven months later, it was repealed. President Franklin Roosevelt re-instated it for good in 1942.
