The six-month passport rule
Many destinations require your passport to remain valid for six months beyond your arrival date, and some airlines will refuse boarding rather than risk it. Because the rule is written in months, the date above — not the 180-day count — is the one to check your expiry against.
If your passport expires close to that date, renew before travelling. The margin exists to cover unplanned extensions to your stay.
Between 181 and 184 days
Six calendar months spans 181 to 184 days depending on the starting month and leap years, so it is always a little longer than 180 days. Half of 365 is 182.5, which no whole calendar interval can match exactly.
Frequently asked questions
What date is 6 months from today?
6 Months From Today is Saturday, 27 March 2027. That is day 86 of the year and falls in ISO week 12. The date is recalculated every day, so this answer is always for today.
How many days is 6 months?
No, not exactly. 6 Months from today is Saturday, 27 March 2027, against Friday, 26 March 2027 for 180 days — a difference of 1 day.
What date was 6 months ago?
6 Months Ago was Friday, 27 March 2026. Counting backwards follows the same rule as counting forwards: every calendar day is included, weekends and public holidays alike.
Does the calculation include weekends and holidays?
Yes. This is a calendar-day count, so Saturdays, Sundays and public holidays are all included. If your contract or deadline is written in "working days" or "business days", it needs a different count.
Which timezone does this use?
Your own. The page is generated in UTC and then corrected in your browser to your device's local date, so the answer matches the calendar on your phone or computer.
What happens if today is the 29th, 30th or 31st?
The count keeps the same day number and moves the month forward, clamping to the last day of the target month when that day does not exist. So one month from 31 January is 28 February (29 in a leap year), not 3 March.
