when do we lose an hour

In 2025, we lose an hour when we "spring forward" for daylight saving time on Sunday, March 9, at 2 a.m., when clocks move ahead to 3 a.m. This is the time we lose an hour of sleep. Conversely, we gain an hour when daylight saving time ends and clocks "fall back" on Sunday, November 2, at 2 a.m., moving back to 1 a.m. This switch adjusts the clock to standard time and gives one extra hour of sleep.
