Time Calculator is a tool that adds or subtracts multiple time values (hours, minutes, seconds) and displays the total as H:M:S, decimal hours, total minutes and total seconds.
It is for freelancers filling out timesheets, PMs tallying billable hours, and office workers calculating shifts, breaks or overtime.
Enter each time block in hours, minutes and seconds, choose + or − for each row, and the running total updates instantly in multiple formats. Add or remove rows as needed.
It eliminates mental arithmetic errors when summing multiple time blocks, making timesheet entry and billing calculations faster and more accurate.
