About the Days Since Calculator

This calculator compares a past date to today and reports exactly how much time has elapsed, the mirror image of a days-until countdown.

Formula: Days Since = Today − Past Date, also expressed in full weeks and approximate years.

Useful for tracking sober dates, "days since last incident" counters, how long ago a milestone happened, or how old a purchase or subscription is.
