This calculator helps tourists visiting Thailand determine exactly when they must leave to avoid overstaying — no guesswork, no stress.
Simply enter your arrival date and the number of days granted on entry (typically shown on your entry stamp), and we'll calculate your last permitted day using Thai immigration calendar-day counting rules.
Thai immigration counts tourist stays by calendar days, starting from your arrival day. This calculator applies the official method to give you a clear, accurate exit date.
The number of days granted depends on your nationality, visa type, and current Thai immigration policy. Always verify your allowed stay with the stamp in your passport or official Thai immigration sources.
Use this tool to confidently plan return flights, accommodation bookings, and travel within Thailand without worrying about overstaying.
Verify with your entry stamp: Thai immigration rules may change, and individual cases can vary. This calculator provides an estimate based on standard tourist entry rules.
Not legal advice: Always rely on your actual entry stamp or confirmation from Thai Immigration for final travel decisions.
