How Many Days Until Martin Luther King Jr. Day 2026?

Martin Luther King Jr. Day 2026 is Monday, 19 January 2026

Martin Luther King Jr. Day 2026 fell on Monday, 19 January 2026, which was 212 days before 19 August 2026. That is 30 weeks and 2 days, or 147 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 2026-01-19 in ISO form and 1/19/2026 in the US format, it falls in ISO week 4 of 2026, and it is day 19 of 365.

How the date of Martin Luther King Jr. Day is decided

The third Monday in January, so it falls between 15 and 21 January. It has been a federal holiday since 1986.

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 2026 that is 19 January.

Martin Luther King Jr. 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.
