The six-month passport rule is counted in months, not days
Many countries require a passport to remain valid for at least six months beyond your date of entry. That requirement is written in months, so the safe reading is the calendar date six months ahead — which, as the comparison above shows, is typically one to five days later than 180 days.
When a rule is stated in months and you count in days, you can arrive at an answer that is a few days too early. For passport validity, always take the later of the two dates.
The rolling 180-day window
Short-stay travel limits usually pair 180 days with a 90-day allowance: at any moment you look back 180 days and count the days already spent. The window moves with you rather than resetting on a fixed date, so the answer above is the start of the window for someone checking today, not a deadline.
