How the Federal Holiday Observed-Date Calculator Works
US federal holidays with a fixed calendar date — like Independence Day on July 4th or Christmas on December 25th — don't just get skipped when they land on a weekend. Instead, the federal government shifts the day off to the nearest weekday through an observed-date rule: a holiday falling on Saturday is observed the preceding Friday, and one falling on Sunday is observed the following Monday. Pick a holiday and a year, and this calculator shows you the actual calendar date, its day of the week, and the observed date federal offices will actually close.
This matters for anyone tracking bank closures, mail delivery (USPS), and federal office hours, since those all typically follow the observed date rather than the calendar date. It also flags whether the holiday lines up into a three-day weekend — either because it naturally falls on a Monday or Friday, or because the weekend adjustment pushed it there.
Not every US holiday works this way — floating holidays like Thanksgiving (fourth Thursday of November) or Memorial Day (last Monday of May) are defined by weekday position, not a fixed date, so they never need this kind of adjustment. See the FAQ below for how the rule applies in practice.
Frequently Asked Questions
When a fixed-date federal holiday falls on a weekend, it's observed on the nearest weekday: a Saturday holiday is observed the preceding Friday, and a Sunday holiday is observed the following Monday, so federal offices still get the day off.
No. Thanksgiving is defined as the fourth Thursday in November, so it always falls on a weekday and never needs an observed-date adjustment. This rule only affects holidays with a fixed calendar date, like July 4th or Christmas.
No. The observed-date rule is a federal government policy for federal employees and offices. Private companies, banks, and the stock market set their own holiday schedules and may or may not follow the same observed dates.
