How it counts
- Working days are Monday to Friday.
- Singapore public holidays are skipped, including the observed Monday when a holiday falls on a Sunday.
- A holiday on a Saturday changes nothing: Saturday is already not counted.
- When adding, the start date is not counted. When counting between dates, both dates are counted, and the count without the start date is also given.
- Dates from 2026-01-01 to 2027-12-31 only, the years with official MOM holiday data loaded here.
- Company-specific off days are not included.
