The start date itself is not counted; counting begins with the next business day.

How the count works

Every date in the range is classified as a weekday or a weekend day; listed holidays falling on weekdays are then removed. For adding business days, counting starts from the next working day after the start date — so “10 business days from Thursday 1 October” lands on Thursday 15 October.

Worked example

October 2026, both ends counted

  1. October has 31 days, starting on a Thursday
  2. Weekend days: 5 Saturdays and 4 Sundays = 9
  3. 31 − 9 = 22

22 business days (before any holidays).
