How to Use the Date Calculator
This Date Calculator
is really of great assistance especially
if you're dealing with counting off days, months or years. Even getting
the date duration between two dates is quite time-consuming counting them
manually.
For instance, you want to get how many days or months are there between
March 1, 2022
up to April 13, 2025
. Counting
them from your calendar is really time consuming, but with this calculator
it will just be a breeze and the results are accurate.
Another example, adding few days from a starting date is quite easy if
it's just adding up 5 days or 7 days. However, if you are dealing with
adding 140
days or subtracting 640
days, that's
another story.
The calculator is built so that doing these three examples will be a lot easier and faster for you. You just need to select the right operation type and enter your inputs.
The calculator is grouped into three (3) parts, the first set is marked
with ⚙️ Operation Type
where you can select the operation you
want to perform (functionality). The second set is the main one where
there's input fields and buttons. The third is the result area where it
displays the outcome of the calculations.
