Working Day Calculator UK

If you've ever worked in conveyancing, HR, or construction in the UK, you've done the finger-on-calendar thing. Someone gives you a deadline in "working days" and suddenly you're squinting at a wall planner, counting squares, trying to remember whether the late May bank holiday falls on the 26th or the 27th this year — and whether that even matters for Scotland. It's a surprisingly common problem. Working day deadlines are embedded throughout UK professional life: notice periods in employment contracts, completion timelines in property transactions, response windows in construction adjudication, even HMRC filing deadlines. And getting them wrong isn't just embarrassing — it can have real consequences. Miss a contractual deadline by a day because you forgot the Easter Monday bank holiday and you've got a genuine problem on your hands. I looked online for a tool that could help and found dozens of generic date calculators. The trouble was, most of them were US-focused. They'd exclude Thanksgiving and Independence Day, which is no help when you're trying to work out a completion date in Leeds. The ones that did offer UK support often lumped England, Wales, Scotland, and Northern Ireland together, despite the fact they don't all share the same bank holidays. Scotland has its own set, Northern Ireland adds St Patrick's Day and the Battle of the Boyne — get the wrong list and your calculation is quietly off by a day or two. So I built [Working Day Calculator](https://workingdaycalculator.co.uk). The idea was simple: you enter a start date and a number of working days, and it tells you the exact end date, correctly excluding weekends and the right bank holidays for your part of the UK. Or you give it two dates and it counts the working days between them. That's it. No account, no sign-up, nothing to install. The UK version was actually one of seven country-specific sites I ended up building — I started with New Zealand (where I'm based), then added the UK, Australia, Canada, Hong Kong, Ireland, and Singapore. Each one uses the correct public holiday calendar for that jurisdiction, and I update them every year when new dates are confirmed. What surprised me was who started using it. I'd assumed it would mostly be HR teams calculating notice periods, but it turned out property lawyers and conveyancers were some of the heaviest users. Working day deadlines run through the entire conveyancing process — completion notices, requisition response windows, exchange-to-completion timelines. Having a tool that handles the bank holiday question reliably saves a genuine chunk of time when you're juggling multiple transactions. It's free and it'll stay free. I built it because the problem annoyed me, and it turns out it annoys a lot of other people too. If you spend any part of your week counting working days on a calendar, give it a go — you'll wonder why you didn't look for it sooner. **[workingdaycalculator.co.uk](https://workingdaycalculator.co.uk)**
