Quick answer: excluding company closure days business days

  • Add closure days as custom holidays to remove them from business day counts.
  • Name closures clearly and set the correct year, especially over New Year.
  • Combine closure days with public holiday presets for full coverage.

What counts as a closure day

Closure days include office shutdowns, maintenance windows, inventory counts, and regional closures that stop work. Treat them like holidays so they drop out of workday totals.

How to add as custom holidays

Use the custom holiday list in the calculator. Add clear names and correct dates for each closure. If the closure repeats yearly, update the year to match your range.

Naming and year boundary tips

  • Name closures descriptively (e.g., “Year-end shutdown”).
  • For ranges crossing New Year, add closure dates in both years.
  • Keep a shared list so teams use the same assumptions.

Worked examples

Example A: Week-long shutdown

Add Mon–Fri closure; Sat–Sun weekend.

Result: removes 5 business days.

Example B: Maintenance Friday

Add one Friday closure.

Result: removes 1 business day.

Example C: Cross-year shutdown

Add closures Dec 28–31 and Jan 2.

Result: removes 3 business days in that span.

Common mistakes

  • Not adding closure days at all.
  • Using the wrong year for recurring closures.
  • Leaving weekend pattern incorrect for the region.
  • Not sharing the custom holiday list with stakeholders.
