Time Math
Add or subtract hours and minutes from a clock time. The result wraps at midnight and does not name the next calendar day.
Frequently asked questions
How is this different from the time calculator?
Time math shifts one clock time by a duration. The time calculator also handles durations between two times.
What happens at midnight?
The clock wraps. A result before 0:00 or at 24:00 or later is marked as crossing midnight.
