Calculate the end date of a notice period counted in working days. The calculator runs entirely in your browser and pairs a focused answer with the method, assumptions and the related tools worth checking next.
Your inputs stay in this browser tab. Nothing is sent to a server to produce the result.
Review the inputs and select Calculate.
Enter the date notice was served and the notice length in working days, pick a weekend pattern (Saturday & Sunday by default) and optionally a public-holiday calendar. The calculator steps forward one calendar day at a time, skipping weekend days and any holidays in the selected calendar, and reports the end date with its weekday, the holidays skipped and the total calendar days elapsed. It counts the days of the period only — it does not apply any particular contract or workplace rule.
Counting starts the day after the served date. Each following day is checked against your weekend pattern and, if you chose one, the holiday calendar; only days that pass both checks reduce the remaining notice. A negative number of days counts backwards from the served date instead. Edge case: if the served date is a Friday, the count effectively starts on Monday, because Saturday and Sunday are skipped first.
With the Saturday & Sunday weekend and no holiday calendar, the working days run 3, 4, 5 and 6 March, then 9 to 13 March, and the tenth working day is Monday 16 March 2026 — 14 calendar days after service. Serving the same notice on Friday 6 March with 5 working days ends on Friday 13 March 2026.
The result is a date count, not a ruling on any individual notice period: whether the served day itself counts, how part-days are treated and which holidays apply can depend on the agreement involved, and those rules are not encoded here. If no holiday calendar is selected, public holidays are counted as ordinary working days.
Enter the date notice was served and the number of working days, then select Calculate. Each step below is a short action rather than a wall of explanation.

The calculator steps forward one calendar day at a time from the day after notice was served. Each day is checked against your weekend pattern and, if you selected one, the holiday calendar; only days that pass both checks count down the notice, and the date the count runs out is the end date.
No: counting starts the day after the served date. In the page's worked example, notice served on Monday 2 March 2026 with 10 working days runs through 3 to 6 March and 9 to 13 March, ending on Monday 16 March 2026, 14 calendar days after service.
The weekend pattern decides which days never count: Saturday and Sunday by default, with Friday and Saturday, Sunday only, or none as alternatives. A holiday calendar additionally skips that country's public holidays; if none is selected, public holidays are counted as ordinary working days.
Because the next two days are weekend days under the default Saturday and Sunday pattern, they are skipped before the count begins. Serving the same notice on Friday 6 March 2026 with 5 working days therefore ends on Friday 13 March 2026.
A negative number of working days counts backwards from the served date instead. Either way the result is a date count, not a ruling: whether the served day itself counts, how part-days are treated and which holidays apply can depend on the agreement involved, and those rules are not encoded here.
