Choose a date and time calculator
How long have you been together?
Use the dating time calculator to measure the time between your relationship start date and today or a date you choose. See completed calendar years and months, total elapsed days, your next anniversary and hundred-day milestones.
Just here for a little fun? Your first date, the day you became official or your wedding date can all be a starting point. The calculator counts calendar time, not compatibility. Its month-end and leap-day conventions are explained on the tool page.
