Adding time spans: summing hours and minutes

For timesheets, projects and travel times

The Time Span Calculator adds up multiple time spans in HH:MM format and outputs the total duration in hours and minutes as well as a decimal number. It also calculates the average of all entered spans – useful for weekly evaluations.

Typical use: enter the daily working hours for a week and see the weekly total at a glance. Or: add up several project phases in hours for a timesheet for the client.
