How this works
A working day here is a Monday to Friday that is not a Singapore public holiday. Public holidays are MOM's gazetted dates for 2026 and 2027, including in-lieu Mondays when a holiday falls on a Sunday (for example Monday 9 November 2026 for Deepavali). Holidays that fall on a weekend are not counted twice.
Counting between two dates includes both the start and end dates by default; switch off "Count the start date" to start from the next day. Adding working days never counts the start date itself, so 3 working days after Thursday 5 November 2026 is Wednesday 11 November 2026.
Turn on "Saturday is a working day" for a six-day work week. Contracts, notice periods and statutory deadlines can define working days differently, so check the wording of the document you are counting for.
