Leave blank if ACAS EC was not used

Note: This calculator assumes a 3-month limitation period (e.g. unfair dismissal, discrimination, unlawful deductions). ACAS early conciliation extensions are calculated in accordance with s.207B Employment Rights Act 1996. The clock stops from the day after Day A to Day B (s.207B(3)). If the limitation period would expire during the period from Day A to one month after Day B, it is extended to one month after Day B (s.207B(4)).
