When a year is 366 days
If 29 February falls between today and the same date next year, the interval is 366 days rather than 365. That is why "one year" and "365 days" can give different dates, and the comparison above shows whether they differ for a count starting today.
The 29 February date itself is the edge case: one year from 29 February 2028 has no matching date in 2029, so the convention is to use 28 February.
The weekday moves by one — or two
Because 365 divided by seven leaves a remainder of one, the same date next year normally falls one weekday later. When a leap day intervenes it moves by two. That is why your birthday drifts through the week rather than staying put.
Frequently asked questions
What date is 1 year from today?
1 Year From Today is Monday, 27 September 2027. That is day 270 of the year and falls in ISO week 39. The date is recalculated every day, so this answer is always for today.
Is one year always 365 days?
Yes, they match exactly. 1 Year from today is Monday, 27 September 2027, against Monday, 27 September 2027 for 365 days — a difference of no days.
What date was 1 year ago?
1 Year Ago was Saturday, 27 September 2025. 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.
