## Key Features of the Date Calculator

The date calculator can come in handy for you in various cases. Firstly, you can calculate what date will be if you add or subtract a certain period of time to the original date. So you can calculate the date you need.

Another use case suggests the opposite. You know two dates and you need to calculate what time period separates these two dates. Moreover, you can calculate this period not only in days but also in other units of time - seconds, minutes, hours, weeks and even years. What is important, not only the start and end dates can be taken into account, but also the exact time (if necessary). So you can get the result you need with extreme accuracy. For your convenience, you can easily copy all the results in one click.

The process of selecting the start and end dates is very convenient and simple. You can enter all the data using the keyboard, or mark the desired dates in the drop-down calendar.

**Example:**

Imagine that your holidays start on March 27th. You know that this will continue for 24 days. Now you need to know the end date by adding 24 days to the 27th of March. Just enter the date and number of days in the calculator and get a new date - April 20th!

## Date Calculator Between Two Dates

- First, identify the starting and an ending time. The goal is to subtract the starting time from the ending time under the correct conditions.
- If the times are not already in 24-hour time, convert them to 24-hour time. AM hours are the same in both 12-hour and 24-hour time. For PM hours, add 12 to the number to convert it to 24-hour time. For example, 1:00 PM would be 13:00 in 24-hour time.
- Determine whether the number of minutes is larger in the starting time or the ending time.
- If the ending time has a larger number of minutes: Subtract the starting time from the ending time as you would subtract normally, keeping the hours and minutes on the appropriate side of the ':', where hours are on the left, and minutes are on the right. For example:
13:57 – 9:22 4:35 - If the starting time has a larger number of minutes: Treat the hour and minute portion separately. Add 60 to the number of minutes in the ending time, and subtract 1 hour from the hour portion of the ending time. Then, subtract the minutes and the hours, keeping the result on the appropriate side of the ':' where hours are on the left, and minutes are on the right. For example:
13:57 – 9:58 ⇒ 12:117 – 9:58 3:59

- If the ending time has a larger number of minutes: Subtract the starting time from the ending time as you would subtract normally, keeping the hours and minutes on the appropriate side of the ':', where hours are on the left, and minutes are on the right. For example:
