How Many Days Until Columbus Day 2028?

Columbus Day 2028 is Monday, 9 October 2028

There are 782 days between 19 August 2026 and Columbus Day 2028, which falls on Monday, 9 October 2028. That is 111 weeks and 5 days, or 534 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 2028-10-09 in ISO form and 10/9/2028 in the US format, it falls in ISO week 41 of 2028, and it is day 283 of 366.

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 2028 that is 9 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 534 working days above.
