CalculatorLeave days
Count working and leave days in a date range.
Three 2026 long-break plans: calendar days are not leave days
These examples assume a Monday-to-Friday schedule and exclude weekends and gazetted public holidays. Company calendars, shifts and time off in lieu still need confirmation.
Four leave days for a nine-day break
- Input
- Break from 28 Mar to 5 Apr 2026; five-day work week
- Result
- Four leave days; Good Friday on 3 Apr and two weekends are excluded
- What it means
- Place public holidays and weekends on the calendar first instead of assuming all nine days consume annual leave.
A break around National Day
- Input
- Break from 8 Aug to 16 Aug 2026; five-day work week
- Result
- Four leave days; 10 Aug is the observed National Day holiday, plus two weekends
- What it means
- An observed Monday holiday changes the working-day count, so the festival date alone is insufficient.
Nine days around Christmas
- Input
- Break from 19 Dec to 27 Dec 2026; five-day work week
- Result
- Four leave days; Christmas Day on 25 Dec and two weekends are excluded
- What it means
- The calendar combination finds workdays to cover; it does not mean the employer will approve every date.
How should you use the calculated result?
The tool checks each day in the range and counts only Monday-to-Friday dates that are not Singapore public holidays. Use it to budget leave, then confirm against the company calendar and approval process.
When should you not use this result directly?
- Six-day weeks, rotating shifts, night work and irregular rest days cannot use the Monday-to-Friday result directly.
- Company holidays, substituted holidays, half days, hourly leave and time off in lieu are outside this simplified rule.
- A public-holiday calendar is not leave approval; rosters, business needs and employer policy still control.
