Days Together Calculator

How it works

days together = count-to date − start date (+ 1 if the first day counts) · weeks = days ÷ 7 · years, months, days counted month by month on the calendar · next 100-day milestone = days rounded up to the next multiple of 100 · hours = days × 24, minutes = days × 1,440

The calculator counts the exact calendar days from the day you got together to today, with leap days included, and shows the same span in weeks, in years, months and days (counted month by month, never by dividing by 365), in months alone, and in hours and minutes. By default it counts elapsed days, so the day after you got together is day 1; switch on the first-day option if you count your first day as day 1 too. Couples often celebrate round numbers, so it finds your next multiple-of-100 day, your next big milestone (500, 1,000, 1,111, 2,000 days and so on), your next yearly anniversary with the classic gift theme for that year, and your next monthiversary. A timeline lists the upcoming milestones with their dates and weekdays — including fun ones like 10,000 hours, a million minutes and a billion seconds — and a second table shows the ones you have already passed. Pick a future “count up to” date to see how long you will have been together on a trip, a proposal or a wedding day.

Worked example

Together since February 14, 2018 and checked on October 19, 2026: that is 3,169 days, or 452 weeks and 5 days — 8 years, 8 months, 5 days (104 months, 5 days), about 8.68 years, or 76,056 hours. The next 100-day milestone (3,200 days) is 31 days away on November 19, 2026, the next big one is 3,333 days on Thursday, April 1, 2027, and the 9th anniversary is 118 days away on February 14, 2027 (classic gifts: pottery or willow, or leather). The couple has shared 453 weekends, 8 Valentine’s Days and about 107 full moons so far.
