How Many Days Until Memorial Day 2029?

Memorial Day 2029 is Monday, 28 May 2029

There are 1,004 days between 28 August 2026 and Memorial Day 2029, which falls on Monday, 28 May 2029. That is 143 weeks and 3 days, or 685 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 2029-05-28 in ISO form and 5/28/2029 in the US format, it falls in ISO week 22 of 2029, and it is day 148 of 365.

How the date of Memorial Day is decided

The last Monday in May, so it falls between 25 and 31 May. It has been fixed to a Monday since the Uniform Monday Holiday Act took effect in 1971.

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 28 May.

Memorial 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 observed date is the one our business days calculator skips.

The weekday never changes; only the date does, inside the May 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 685 working days above.
