## How the time calculator works

The Invezz time calculator tool’s main function is to make calculations with units of time as simple as calculations with regular numbers. It does so by working in like units of time (minutes to minutes, etc.), then performing the maths and giving you an exact figure. You can also use our time calculator to perform calculations such as adding time to or subtracting time from a given date.

## Why should I use it?

Simply put, time is money. Having a better understanding of how time works can help you be more efficient in the way you use it. It can be complicated to work out exact periods of time when dealing with different units, and this calculator gives precise figures at the click of a button.

## What to consider when budgeting your time

Here are some other factors to consider when budgeting your time:

**Expect the unexpected.**That simple task that you dismiss with a wave of the hand and a nonchalant “five minutes”? It will probably take longer. Learn to bake unexpected circumstances into how you budget your time.**Understand opportunity cost.**Opportunity cost is an economic term that refers to the rewards you give up by choosing one investment while not making another. Time works the same way: before you go do something that will take up a lot of time, ask yourself if that time could be better spent doing something more productive, or even simply more fun.**Set deadlines for yourself**. Setting deadlines can help you focus better, understanding that you only have a finite amount of time to get a given task done. The result can be more efficient use of your time during productive hours, and thus more time to enjoy leisure.
