Schengen Calculator 90/180 — Track Your 90 in 180 Days Most travellers have more Schengen days left than they think. Because the 180-day window rolls forward, older trips drop out of the count — so your real balance is often better than a simple "90 minus days used" guess. Schengen Calculator shows you exactly how many days you have, and when you get them back. Trusted by travellers since 2015. WHAT IT DOES • Know your exact balance — days used, days remaining, and the latest date you can stay, for any date you choose: today, a planned entry, or a planned exit. • See your days come back — interactive calendar and timeline views show when past trips fall out of the 180-day window and your allowance refreshes. • Plan with confidence — add past, current and future trips and get a clear OK or Overstay indicator before you book. • Check the maths on any day — tap a date to see the full calculation behind it: which trips count, and the running totals. • Always in sync — your trips are stored on your device and kept up to date across iPhone and iPad via your iCloud account. No sign-up required. HOW THE 90/180 RULE WORKS Visitors may spend up to 90 days in the Schengen area within any rolling 180-day period. The window is counted backwards from whichever date you're checking, and both entry and exit days count. Schengen Calculator applies exactly this method — the method published by European authorities — to every calculation. SUBSCRIPTION Full functionality requires an auto-renewing subscription. New subscribers get a 7-day free trial — cancel anytime in Settings. GOOD TO KNOW Schengen Calculator is an independent tool, not an official product of the European Union or any government. Results are for planning purposes — always confirm your position against your passport stamps before you travel.
