Schengen 90/180 Day Calculator

90 Day Rule, Days Left Tracker

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Plan your next Europe trip before you book: see your Schengen 90/180 balance, check every counted date, and track 183-day residency limits. Private and offline. Count your Schengen 90/180 days and tax-residency days in one private travel tracker. Tap any balance to see which dates were counted. Plan a future trip and see how long you can stay before you book. No more counting calendar squares by hand and hoping you got it right. Enter each trip once and KnowDays keeps the running total. It is built for frequent travelers, second-home owners, expats and digital nomads whose stays are capped by a day count: 90 days in Europe, or a 183-day rule. FREE, NO ACCOUNT NEEDED • Add and edit up to 3 stays and see your live Schengen 90/180 balance • See your last counted day before the limit or, once you reach it, the next date a day is freed • Get a warning when a planned stay goes over the 90-day limit • Border summary: your dates in large type to show at passport control (a personal record, not an official document) • Pick a country and KnowDays marks whether it counts toward Schengen, from a dated membership list • Your balance on Apple Watch (app and complications), in Home Screen and Lock Screen widgets, and from Siri • Save a complete backup file (JSON) and restore it at any time • Contact support from the app; "Question about this number?" adds the calculation to your email KNOWDAYS PRO: MONTHLY, YEARLY OR LIFETIME • Unlimited stays, plus a separate record for each traveler you track • The calculation receipt: every stay inside the 180-day window, the days each one used, and the date your count next drops • Allowance calendar: your Schengen allowance on every date • Trip planner: test future dates and compare itineraries side by side before you book • Multiple trackers for days in a country or days outside it, with your own rules: calendar year, a recurring tax year (starting on any date you choose), a rolling window or a custom fiscal period; count any part of a day, nights or full days only; set your own limit, such as 183 days • Opt-in alerts for a low balance, your first day over the limit, and days returning to your balance • Private iCloud sync between your devices, end-to-end encrypted, plus automatic iCloud backups • CSV import, plus PDF reports and CSV export for your advisor • Suggested stays you confirm one by one: from the "Suggest today's country" shortcut when you run it, or from the dates and places in photos you pick, read on your device • Record your reason for any stay you mark as not counted • Offline world atlas and insights, plus Travel Story images and route videos to share BUILT FOR REAL BORDER DATES Entry and exit days both count. Every calculation uses the local calendar dates in your records, so a trip across the International Date Line still lands on the right day. Location is used only for a current-country suggestion that you ask for and confirm; coordinates are never saved. PRIVATE BY DESIGN Your travel records stay on your devices, and iCloud sync stays off until you turn it on. No account, no ads, no tracking SDKs and no analytics uploads. It works offline. A CALCULATOR, NOT ADVICE KnowDays is a planning aid, not legal, tax or immigration advice. A day count alone does not decide tax residence or visa eligibility. Check dates and rules against official records and qualified guidance.
