Audit note

This is a leave-notice or leave-window deadline only, never a pay calculation. Dates are computed to the exact day from the anchor date you enter — always double-check against your own contract and current gov.uk guidance before relying on it for a legal deadline.

Stop tracking this by hand

Statutory leave dates and balances are easy to miscalculate by hand. Tempry tracks every type of leave against the right statutory rules automatically, so notice deadlines and remaining balances are never worked out on a calendar again.

Frequently asked questions

How much notice do I need to give for paternity leave?
28 days before the date you want each period of paternity leave to start — the calculator works out the exact deadline from your intended start date.
Does this apply to each of my two weeks separately?
Yes — if you're splitting your 2 weeks into non-consecutive blocks, the 28-day notice applies to each block's start date.
Do I need 26 weeks of service to give this notice?
No — since 6 April 2026 paternity leave is a day-one right, so the notice period applies from your very first day of employment.
