Why use this site?
Government guidance is accurate, but the part you need (your own date) is often spread across several pages. Each tool here asks a few questions and gives you your dates, with links back to the official rules so you can double-check.
Everything is free. The site is paid for by adverts and, where useful, links to software or services. We'll always make it clear when a link is one of those.
