How this calculator works

This calculator walks month by month between your two dates, carrying over any leftover days, so the years-months-days breakdown lines up with a real calendar rather than a flat day-count average. It also converts the same span into weeks, months, hours, and minutes, since different situations call for different units — payroll cares about weeks, medical dosing schedules care about hours, and legal documents often want the precise day count.

Formula

difference = end date − start date, normalized to Y / M / D, then re-expressed in weeks / months / hours / minutes
