Calendar Days vs Working Days for Notice Periods

The same number of notice days can produce very different end dates. The difference starts with what your contract means by a ‘day’.

Calendar days

Calendar-day notice counts every date in sequence: weekdays, weekends and usually public holidays. If notice starts on 2 September, that date is day one under inclusive counting.

Working days

Working-day notice counts only the weekdays your employer treats as working days. A Monday–Friday office skips Saturday and Sunday; a Monday–Saturday workplace skips only Sunday. Shift patterns may require a custom week.

Weekends and holidays

Weekends are not automatically excluded from every notice period. Public and company holidays may count in calendar notice but be excluded in working-day notice. Policies differ, and an external holiday calendar cannot determine your contractual rule.

Example: 30 calendar days

If notice starts on 2 September 2026, 30 calendar days ends on 1 October 2026. Every intervening weekend is counted.

Example: 30 working days

With a Monday–Friday week and no excluded holidays, 30 working days starting 2 September 2026 ends on 13 October 2026. The six weekends make the calendar span longer.

What to check

Read the notice clause in your employment contract and any HR policy defining when notice begins, whether days are calendar or working days, how leave is treated, and what happens when notice ends on a non-working date. Ask HR when wording is unclear.
