About Notice Period End Date Calculator

Notice runs in calendar time, so four weeks from 15 September 2026 ends on 13 October regardless of weekends. Within that period there are 20 working days, and six days of owed holiday taken during notice reduces attendance to 14 - which is the figure that matters for handover planning.

Formulas

Notice end date

end = notice date + weeks x 7 calendar days

Days to serve

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or fees or charges into account.
  • Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Can holiday be taken during notice?

Usually yes, and employers can often require it, though contracts and local law vary. Untaken leave must otherwise be paid out.

Does notice start the day it is given?

Typically the following day, and in some contracts from the next pay period. Check the contractual wording.
