Clock Changes 2027: When Daylight Saving Time Starts Again on March 14 in the U.S., UK, Europe and Australia

Daylight saving time (DST) starts again in the U.S. on Sunday, March 14, 2027, at 2 a.m. local time, under federal law, after clocks fall back this Sunday, Nov. 1, 2026. Title 15, section 260a of the U.S. Code runs DST from “2 o’clock antemeridian on the second Sunday of March of each year” to “2 o’clock antemeridian on the first Sunday of November”. That puts the 2027 end on Sunday, Nov. 7. The fall-back day itself has its own page: see our Nov. 1, 2026 story, which also covers where the Sunshine Protection Act stands. For the standing rule, see when daylight saving time starts and ends each year.

GOV.UK says UK clocks go forward 1 hour at 1am on the last Sunday in March and back at 2am on the last Sunday in October. In 2027 those Sundays are March 28 and Oct. 31.

Period	New York to London gap
