It displays time and date values accurately, enabling users to fix a past or future date and compute the difference from the present time. The extension supports practical applications such as demurrage calculation, medical treatment timing, retirement countdown, and age calculation.

In addition to basic time difference calculations, Time Calculator estimates physiological counts like heartbeats and breaths over a lifetime using customizable multipliers for different species. It also functions as a stopwatch and countdown timer.
