Calculating Work Hours & Payroll
Accurately tracking billable hours is critical for freelancers and employees alike. Use this tool to sum up your daily shifts. For example, if you worked 4 hours 30 minutes in the morning and 3 hours 45 minutes in the afternoon, simply add them here to get your total daily duration. You can also subtract lunch breaks by switching the operation to subtract.
Event Planning & Project Management
Need to know if your presentation slides fit within the allotted time? Or how long a series of tasks will take? Enter the duration of each segment to see the total time required. This is especially useful for video editors and producers calculating total runtime.
How Time Math Works
Unlike standard decimal math, time follows a sexagesimal (base-60) system. When seconds exceed 60, they carry over to minutes. When minutes exceed 60, they carry over to hours. Our calculator handles these conversions instantly, so you don't have to manually calculate that 90 minutes equals 1 hour and 30 minutes.
