Common mistakes
- Counting a holiday that falls on a weekday as a normal workday.
- Using a national calendar when a state, province, school, bank, or employer calendar is different.
- Forgetting that observed dates can differ from the holiday date printed on a wall calendar.
Monthly capacity check
A team needs the Singapore workday count for a 2026 planning month.
Use the monthly table, then subtract company closures that are not in Singapore public holidays 2026.
Employer calendars, banking calendars, and carrier calendars can differ from national holiday lists.
Quarter planning
A release plan spans a full quarter.
Use quarter totals before assigning weekly capacity or SLA windows.
