In 2023, clocks fall back on November 5 at 2:00 AM local daylight time, when clocks are set back one hour to 1:00 AM standard time. This marks the end of Daylight Saving Time in most of the United States and Canada, giving an extra hour of sleep and earlier sunrise and sunset times.
This is consistent with the general rule that Daylight Saving Time ends on the first Sunday of November in the US, which for 2023 is November 5.
