Which way do the clocks go?
Spring forward: at 2 a.m. the clock jumps to 3 a.m., so you lose an hour of sleep — but sunset lands an hour later, kicking off the bright-evenings half of the year. Phones update themselves; the microwave does not.
A century of arguing about it
The U.S. first tried daylight saving in 1918, repealed it, brought it back in WWII as 'War Time,' and standardized it in 1966. Congress regularly debates making it permanent — the Senate even passed a bill in 2022 — but the twice-a-year ritual survives.
