How Many Days Until Labor Day 2029?

Labor Day 2029 is Monday, 3 September 2029

There are 1,111 days between 19 August 2026 and Labor Day 2029, which falls on Monday, 3 September 2029. That is 158 weeks and 5 days, or 759 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 2029-09-03 in ISO form and 9/3/2029 in the US format, it falls in ISO week 36 of 2029, and it is day 246 of 365.

How the date of Labor Day is decided

The first Monday in September, so it falls between 1 and 7 September.

That makes it a floating date: it is pinned to a weekday rather than to a day number, so it is always a Monday but the date moves. In 2029 that is 3 September.

Labor Day is one of the eleven US federal holidays. Federal offices, banks and the bond market close, and it does not count as a business day in any of the business-day calculators on this site. Because the rule always puts it on a Monday, it can never land at a weekend, so it never needs an observed-date shift.

The weekday never changes; only the date does, inside the September window the rule allows.

Every convention used above — whether the start date counts, how month ends are clamped, which holidays close an office — is written out on the methodology page, including how we count the 759 working days above.
