Add each period you spent in a country (arrival and departure date, both days counted). Pick the year; the tool totals days per country and flags countries near or over 183 days.
For every period, only the days that fall inside the chosen counting period are counted, and both the first and last day are included. Overlapping periods in the same country are not double counted. Days are totalled per country name exactly as you type it.
Turkey 1 Jan–30 Jun and Germany 1 Jul–20 Jul in the same calendar year: Turkey shows 181 days (1 more day before reaching 183), Germany 20. Press “Load example”.
Is 183 days always the tax residency rule? No. Many countries use 183 days as one test, but others add home, family, centre-of-interests or rolling multi-year tests. Check your own country and any tax treaty.
Does a partial day count? This tool counts every calendar day from arrival to departure inclusive. Some tax authorities count arrival or departure days differently.
Is my travel history sent anywhere? No. All counting happens locally in your browser.
