How Many Days Until Daylight Saving Time starts 2026?

Daylight Saving Time starts 2026 is Sunday, 8 March 2026

Daylight Saving Time starts 2026 fell on Sunday, 8 March 2026, which was 164 days before 19 August 2026. That is 23 weeks and 3 days, or 114 working days once Saturdays, Sundays and the US federal holidays in between are taken out — the figure that matters if you are counting delivery lead time or a work schedule rather than sleeps. The date is 2026-03-08 in ISO form and 3/8/2026 in the US format, it falls in ISO week 10 of 2026, and it is day 67 of 365.

How the date of Daylight Saving Time starts is decided

In the United States, the second Sunday in March at 2:00 am local time, when clocks go forward one hour. The European Union changes on the last Sunday in March, so for a few weeks the usual offsets between US and European zones do not apply.

That makes it a floating date: it is pinned to a weekday rather than to a day number, so it is always a Sunday but the date moves. In 2026 that is 8 March.

Daylight Saving Time starts is an observance rather than a federal holiday. Offices, banks and schools stay open unless an individual employer chooses otherwise, and it counts as an ordinary business day in every calculator here. Only the eleven federal holidays are treated as non-working days — the list and the reasoning are on the holiday sources page.
