Looking for a Schengen calculator UK travellers can actually rely on? Since Brexit, British passport holders get 90 days in any rolling 180-day period in the Schengen Area — and the rolling window is genuinely hard to track by hand. The calculator below does it for you: add your trips, and it shows your days used, days remaining, latest safe exit date, and the earliest date you can return with a full allowance.
How the 90/180 rule works for UK passport holders
Since January 2021, UK citizens are “third-country nationals” in EU terms — the same category as Americans and Canadians. The deal is: 90 days in any rolling 180-day period, across all 29 Schengen countries combined, visa-free. Spain, France, Italy, Portugal and the rest all draw from one shared pool of days.
The part that catches people out is the word rolling: the 180-day window moves forward every single day and never resets on a fixed date. Coming home to the UK doesn’t pause it, and a short hop across the Channel doesn’t refresh it. Each day you use becomes available again exactly 180 days later — one day at a time.
This page keeps the rule summary short because we’ve covered it in depth elsewhere: see how long can Brits stay in Europe for the full UK picture, and the complete 90/180 rule guide for the mechanics with worked examples.
Why Brits need to track their days since Brexit
Two things changed the stakes. First, Brexit ended unlimited stays — habits formed over decades (whole winters in Spain, long summers in France) now collide with a 90-day cap. Second, since April 2026 the EU’s Entry/Exit System (EES) records every border crossing electronically, with biometrics. Border officers see your exact day count on screen; overstays are flagged automatically, even by a single day.
One common mix-up while we’re here: the UK ETA is Britain’s entry permission for visitors to the UK — it has nothing to do with your Schengen days. The EU equivalent, ETIAS, is expected in late 2026 and will be a €7 online registration for Brits travelling to the Schengen Area. Neither changes the 90/180 limit.
Three common UK scenarios
1. The Spanish second home
You own a place on the Costa Blanca and want maximum time there. Your ceiling is 90 days per rolling window — owning property changes nothing, and with multiple shorter visits the math gets unintuitive fast. Set the calculator’s control date to your next planned entry and check the “days you can stay” figure before booking flights. Spain-specific rules, the Canary Islands question, and the “Spain to scrap the rule?” headlines are covered in the 90 day rule in Spain.
2. The French holiday home, in weekend doses
A long weekend every few weeks feels harmless — but entry and exit days both count as full days, so a Friday-to-Monday trip costs 4 days, not 2. Ten of those in six months is 40 days gone. Add every trip to the calculator, including the short ones; the short ones are exactly where hand-counting goes wrong.
3. The EU business traveller
Frequent client visits to Germany, the Netherlands or Ireland? Note that Ireland is not in Schengen — those days don’t count — while almost everywhere else in the EU does. If your travel is genuinely frequent, your effective planning question becomes “what’s my latest safe exit on this trip?”, which is precisely the number the calculator’s planning mode gives you.
UK-specific questions
Does time in the UK count toward my Schengen days?
No. The UK is outside the Schengen Area, so days at home don’t count toward your 90 — but they don’t speed up recovery either. Your used days expire on their own schedule, 180 days after each was used, wherever you are.
I have dual UK/Irish citizenship — does the 90/180 rule apply to me?
If you hold Irish citizenship, you’re an EU citizen with freedom of movement — the 90/180 rule does not apply when you travel on your Irish passport. Enter and exit the Schengen Area using the Irish passport and there is no day limit. This is one of the most valuable and least-known facts for the millions of Brits entitled to Irish citizenship.
What’s the difference between the UK ETA and ETIAS?
They’re mirror images. The UK ETA is for non-British visitors entering the UK. ETIAS (expected late 2026) is for non-EU visitors — including Brits — entering the Schengen Area: an online registration and €7 fee, valid three years. Neither is a visa, and neither changes the 90-day limit.
Can I use this as a 90 day rule after Brexit calculator?
Yes — that’s exactly what it is. The post-Brexit rule for UK citizens is the standard Schengen 90/180 rule, and this calculator tracks it: enter your trips since your last 180 days began, and it shows your remaining days and safe dates. It works identically for trips planned months ahead.
Is this the same as the official EU calculator?
The counting logic is verified against the official EU Short-Stay Calculator on 8 test scenarios — same rules, same numbers. What we add is what the official tool lacks: saved trips, a planning mode with your latest safe exit and earliest return dates, and a mobile-friendly interface.
