Passport Validity Date Calculator

Check whether a passport meets destination validity requirements.

About Passport Validity Date Calculator

Validity is assessed on the entry date rather than today, so a passport valid for eight months fails a six-month rule for travel three months away. Airlines enforce this at check-in and deny boarding. Being denied boarding for passport validity is not covered by most travel insurance, which makes it an entirely uninsured loss.

Formula

Passport Validity Date

Validity on entry = months until expiry − months until travel

six-month rule: Many countries require six months validity beyond the entry date
renew by: Latest point at which renewal still preserves compliance
