To find new time after adding hours and minutes to a given time, use clock time calculator.

First of all, note down the start and the end time of each task as recorded in the time card. Next, we calculate hours worked with the following steps:-

**Step I.** First we calculate time duration of all entries or tasks in minutes. See the formula section on time difference calculator for details.

**Step II.** Next, we add up all the minutes from *Step I* and divide the total by 60 to find the hours worked. To find the time spent in *hours and minutes*, we use whole number division. Dividing the total minutes by 60, the quotient will yield the hours and the remainder will give the leftover minutes.
