We built a visa calculator: how many days you and your van have left in every country
Winter in Cyprus, spring in Turkey, summer in Georgia — every country counts your days its own way, and your van has a separate count of its own. Add your stays to the calculator and see, for each country, how many days are left and the date you need to leave by. No more sums in your notes before every border.
Four years on the road: winter in Cyprus, spring in Turkey, summer in Georgia. Turkey gives you 90 days in any 180, Georgia gives a year per entry, Cyprus has its own way of counting, and in every country your van gets a separate allowance on top. Usually all of this lives in your phone's notes and gets recounted by hand before every border. So that counting stops being your job, we built a visa calculator.
A trip log instead of a table in your notes
You add your stays — country and dates — and the calculator sorts them by country. Each card shows how many days you've used, how many are left and the date you need to leave by. The log in the screenshot covers 1,374 days on the road and 8 countries: in Georgia there are 235 days left, with exit no later than 25 May 2027; in Turkey 48 of 90 days are used and 42 remain.

The same view shows where you have actually lived these past years, by year and by country. When a residence permit application or a bank asks how many days you spent in a country, the answer is already worked out.
You have a deadline, and so does your van
You are let in by the border guard, the vehicle by customs, and their limits differ. In Georgia a Russian citizen gets a year per entry, while a van up to 3.5 t gets 90 days of temporary import. Above 3.5 t the limit is often shorter, so the calculator asks for the permitted weight. If the van crossed later than you did, it has its own dates, and the counter keeps two tracks at once. The big number is whichever deadline runs out first.

Your plates matter too
The calculator also asks which country your plates are from. Vehicles with Russian plates are not allowed into Schengen, and neither are those with Belarusian plates: the ban covers cars, motorhomes, vans and trailers. They get turned back at the border, and in Latvia and Lithuania the vehicle is confiscated. If you log a Schengen stay in a vehicle with such plates, the calculator won't count days for it — it shows the ban and a link to the EU regulation instead.

The reminder arrives before the border guard does
Every deadline becomes a calendar event: “take the van out of Georgia”, “leave yourself”, “full allowance back in Turkey”. You can add it to Google, Apple or any other calendar as an .ics file. For the border or a residence permit application there's a PDF summary with your dates, your limit and your last permitted day.

There's no sign-up. The log is stored in your browser, and the whole calculation fits into a link — send it to yourself or to a travel companion, and they'll see exactly the same picture. To move your data to your phone there's a code or a QR, and the only thing that reaches the server is an encrypted blob.
How the days are counted
The hard part isn't the number of days, it's how they're counted. Some countries use a rolling window: on any given date, the days from the last 180 count. In others the clock restarts with every entry, and some count by calendar year. Of the 141 countries with a confirmed rule, 77 count per entry, 51 use a rolling 180-day window, 5 a calendar year and another 5 a rolling year. The rules cover 199 passports, which makes 39,601 passport–country pairs. The OpenVan.camp Editorial team checked the counting windows against primary sources: the websites of foreign ministries, border services and customs. A rule backed only by a retelling doesn't make it into the calculation. For vehicles there are 214 temporary import rules, and the calculator uses 159 of them: those confirmed by an official website, two independent checks or manual verification. The day of entry and the day of exit count as full days, just like at the border.
Each passport also has its own page: where you can go visa-free, for how long and how the days are counted. There's also the World passports ranking with a map.
What not to expect
The calculator is a reference, not legal advice. Rules change without notice, so check your dates with the consulate before a border. For 57 countries the window type isn't confirmed yet, and the calculator says so instead of guessing. It won't extend your visa. It just turns “how much longer can I stay” into one number instead of an evening with a calculator and your passport stamps.
