      Relationship dates, worked out for you

      Enter the day you got together and the calculator gives the dates couples usually mark: how many days, how many full months, the next monthiversary (the same day of the month, every month) and the next anniversary.

      When your day does not exist in a month, like the 31st in April, the calculator puts that monthiversary on the last day of the month.

      Questions about days together

      How are the days counted?

      From the date you enter to today, counting calendar days. The day you started is day 0, so the first anniversary of a date falls on day 365 (or 366 across a leap day).

      How do I count how many months we have been together?

      Count full months from the start date: from March 10 to June 10 is 3 months. The calculator does it for you and shows the days left over.

      What is a monthiversary?

      The same day of the month as the day you got together, celebrated every month. If you started on the 31st, months without a 31st use their last day.

      Is my date saved anywhere?

      No. The calculation runs in your browser and nothing is sent or stored.
