Frequently asked questions
What is elapsed time?
Elapsed time is the amount of time between a start moment and an end moment — 2 h 45 m from 1:15 PM to 4:00 PM. Here it's measured live against the current clock since (or until) the moment you enter.
Why does the answer keep changing?
In “since/until now” mode the calculator re-evaluates every second against your device clock — it's a live counter, like a shift countdown.
