Three hundred sixty-five days is one full calendar year.

Three hundred sixty-five days is a common year but not always a year: starting from a date before 29 February in a leap year, it lands one day short of the anniversary. It is fifty-two weeks and one day, which is why a fixed date moves one weekday later each year, and two weekdays later across a leap day.

How we calculate

  • Counts whole calendar days, midnight to midnight, in your local timezone.
  • Counting is exclusive: today is day 0 and is not counted.
  • Business days are Monday–Friday by default (other working weeks are selectable where offered). The holiday-aware result skips public holidays only for the holiday calendar you choose in the calculator: United States, United Kingdom (England & Wales), United Kingdom (Scotland), United Kingdom (Northern Ireland), Ireland, France, Canada, Australia, and Uganda, or your own custom list. There is no default calendar; each result names the one used and lists the excluded days.
  • No login and no server: every result is computed in your browser, so you can verify it yourself.
