This tool allows you to calculate the arithmetic mean of several periods of time expressed in days, hours, minutes and seconds quickly and easily.

### Average time calculator

Unlike other dimensions such as distance or weight, time is measured in units that are not based on decimal, but sexagesimal: 1 hour does not have 100 minutes, but 60. This makes adding or subtracting this type of units quite complicated.

The average time calculator allows you to calculate the arithmetic mean of up to 10 different periods.

You can use it to plan different activities calculating, for example:

- How much time you spend, on average, to study each day.
- Calculate how much time you spend, on average, to carry out similar projects.
- How long it takes, on average, to make a trip.
- Calculate how much time you spend, on average, to cook.

### Instructions

Enter each period of time in a row, broken down into days, hours, minutes and seconds.

Select the operator that corresponds to each period: A plus sign means that its value is added; a minus sign that is subtracted; a 0 means that it is not taken into account in the computation.

The result is automatically displayed below.
