What happens on the 29th, 30th and 31st
Counting months keeps the day number and changes the month — but there is no 31 June or 30 February. The universal convention, and the one this calculator follows, is to clamp to the last day of the target month: three months from 30 November is 28 February (29 in a leap year), and three months from 31 March is 30 June.
Some contracts instead roll forward to the first of the next month. If a deadline matters, check which rule the document uses.
Three months is 89 to 92 days
Depending on where in the year you start, three calendar months spans anywhere from 89 days (1 December to 1 March in a non-leap year) to 92 (1 May to 1 August). That is why "three months" and "90 days" are not interchangeable, and the comparison above shows today's gap.
Frequently asked questions
What date is 3 months from today?
3 Months From Today is Tuesday, 9 February 2027. That is day 40 of the year and falls in ISO week 6. The date is recalculated every day, so this answer is always for today.
How many days is 3 months?
No, not exactly. 3 Months from today is Tuesday, 9 February 2027, against Sunday, 7 February 2027 for 90 days — a difference of 2 days.
What date was 3 months ago?
3 Months Ago was Sunday, 9 August 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.
