What is Time Calculator?
A Time Calculator is a handy online tool to add, subtract, or find the difference between two times or time durations. With this tool, calculations involving hours and minutes become quick and error-free for anyone.
It is especially useful for instantly working out total study time, work durations, or elapsed time between any two activities. This calculator removes confusion associated with manual time arithmetic and avoids common mistakes.
Formula Behind Time Calculator
For adding time: add hours and minutes separately and convert every 60 minutes to 1 hour. For subtraction, subtract minutes and hours; if minutes go negative, borrow 1 hour (60 minutes). Time difference is simply the absolute value of the minute difference between two times.
