How this is calculated
- The period runs from December 1, 2027 through December 31, 2027, counting both the first and last day.
- Calendar weeks start Monday. ISO week-years at the edges can differ from the displayed civil year.
- Business days use Saturday/Sunday weekends and observed nationwide U.S. federal closures for the standard Monday–Friday schedule. These are not state, employer or international closure calendars.
- Actual holiday dates and observed non-working dates are different; a closure can belong to a holiday whose actual date is in the next civil year.
- Holiday rules project the maintained annual federal policy. Exceptional agency/presidential closures and historical calendars before 1986 are not included.
