How Many Days Until Columbus Day 2027?

Columbus Day 2027 is Monday, 11 October 2027

There are 418 days between 19 August 2026 and Columbus Day 2027, which falls on Monday, 11 October 2027. That is 59 weeks and 5 days, or 285 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 2027-10-11 in ISO form and 10/11/2027 in the US format, it falls in ISO week 41 of 2027, and it is day 284 of 365.

How the date of Columbus Day is decided

The second Monday in October, between 8 and 14 October. Several states observe Indigenous Peoples' Day on the same date instead, and many private employers do not close at all.

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 11 October.

Columbus 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 October 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 285 working days above.
