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 2027 that is 18 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. The observed date is the one our business days calculator skips.
