How time duration is calculated
Find elapsed duration between two clock times, optionally spanning midnight, and return the total in hours and minutes. If end time is earlier than start, the calculator interprets it as the next day; use the date calculator for durations across multiple dates. 22:45 to 01:15 is 2 hours 30 minutes when crossing midnight. The calculation validates each input and keeps its stated units explicit. This version accepts hours and minutes; seconds are not modeled. This is an estimate for the stated assumptions; confirm measurements and any applicable professional or local standards before relying on it.
elapsed minutes = end − start, adding one day when crossing midnight22:45 to 01:15 is 2 hours 30 minutes when crossing midnight.
