Travel
Enter a visa expiration date to see exactly how many days remain before it expires.
A visa's printed expiration date is usually the last date it can be used to enter a country, which is a different thing from how long you're allowed to stay once admitted — a visa valid for entry until a certain date might still grant a shorter permitted-stay period starting from your actual arrival. Check your specific visa's terms (and any stamp or authorization given at the border) for the stay-length rule that actually applies, separate from this expiration-date countdown.
Also planning around your passport's own validity? See the Passport 6-Month Validity Checker as well — the two dates are independent and both matter for travel planning.
