Notice Period Calculator
Work out an employee's last working day from a resignation date and notice period.
How the calculation works
Add the notice period to the resignation date to get the last working day. Weeks are converted at 7 days each; months are approximated at 30 days each, since calendar months vary from 28 to 31 days, so a months-based result can land a day or two off a contract that counts to a specific calendar date instead.
Formula
Last Working Day = Resignation Date + Notice Period (converted to days).
Examples
Resigns Aug 10, 2026, 30 days notice
Last working day: Sep 9, 2026
Resigns Aug 10, 2026, 2 weeks notice
Last working day: Aug 24, 2026
