This basic time calculator determines the time difference when you add or subtract days hours minutes or seconds to another date value. You can read more about the method employed below the form.

## How does this basic time calculator function?

This simple time tool allows you to add or subtract days, hours, minutes and seconds to any two given time values. These values can be expressed in days, hours, minutes and seconds. You need to fill in the first line with the value you want to begin with, choose whether you want to add or subtract and then enter the time to be calculated in the second line. You will then be given the result after the adding or subtracting operation. The time calculator simply counts the time while taking into account some basic rules:

- 1 day is equal to 24 hours;
- 1 hour is equal to 60 minutes;
- 1 minute is equal to 60 seconds.

## Example calculations:

- To a value of 5 days, 2 hours, 30 minutes, 45 seconds, by adding 2 days and 45 minutes it results:

Days | Hours | Minutes | Seconds |

7 | 3 | 15 | 45 |

- To a value of 7 days, 3 hours, 30 minutes, 45 seconds, by subtracting 1 day, 6 hours and 45 minutes it results:

Days | Hours | Minutes | Seconds |

5 | 20 | 45 | 45 |

## What can you use the time calculator for?

For instance it can be used to count the time left until specific event take place. So if you know that from event "x" has passed 1 day and 4 hours, and that the next event “y” will take place in 3 days from the moment of event “x”, then by subtracting from 3 days the time that already passed 1 day and 4 hours, the tool will return 1 day and 20 hours left.

It can also be used to count the total time between two specific time values. For instance if you know that already passed 1 day, 2 hours and 39 minutes from a specific day and that you have to wait another 5 days, 3 hours and 45 minutes until a specific event to take place, then by adding to 1 day, 2 hours and 39 minutes the 5 days, 3 hours and 45 minutes the calculation will return the total time of 6 days, 6 hours and 24 minutes.
