Time Calculator adds, subtracts, multiplies, and divides durations, then converts the result into any unit you need. Type 5h 30m + 2h 15m and read the total. Work out 8h 15m × 3, or split 3d 4h ÷ 2. It carries minutes into hours for you, so you never do it by hand. WHAT YOU CAN DO • Add and subtract times: 40h − 6h 30m gives you the difference in one tap. • Multiply and divide a duration by a number: 45m × 12, or 90m ÷ 4. • Convert any result across units, from years down to milliseconds. • Read the answer your way: hours and minutes, decimal hours, or a clock format like H:MM:SS. • Save past calculations to a history and reuse them. • Pick light, dark, or system theme. Theme stays free. COMMON USES • Timesheets and payroll: total the week, subtract breaks, find overtime. • Billing: turn tracked time into round numbers or decimal hours. • Cooking, workouts, and video editing: add up steps and segments. • Planning: split a duration across people or sessions.
