The most confusing part of figuring out your parental leave entitlement is trying to work out if you have been "employed continuously by the same employer for at least 26 weeks by the end of the 15th week before the due date" who's idea was that anyway? so we have created a little tool that will help you.

Use our calculator to work out the dates for statutory maternity leave eligibility. To begin, simply enter the expected due date below:'

Expected date of birth

This is the date the employee needs to have been employed on by the employer to qualify for SMP (Statutory maternity pay)

You/Your employee will qualify for SMP if you/they have been with their employer for 26 weeks by the end of the ‘qualifying week’, which is 15 weeks before the expected week of childbirth. This means they need to have been employed by you from 41 weeks before the baby’s due date.

Maternity pay relevant period (for employers)

This is the relevant period. This is usually the 8 week period before the qualifying week. SMP entitlement depends on your employee’s AWE in the ‘relevant period’.
