How To Use The Deadline Calculator

To use the deadline calculator, simply select the start date and then enter the number of days you want to add. After you have entered this information, click on the “Calculate” button to obtain the result. The result will be displayed in the “Result” field, indicating the date after the specified number of days have been added to the start date.

How It Works

The deadline calculator works by taking the start date provided, converting it into a Date object, and then adding the specified number of days to that date. The final date is then calculated and formatted back into a standard date format (YYYY-MM-DD) to display it in the result field. This is all done using native JavaScript without any additional libraries.

Limitations

The deadline calculator does not take into account public holidays or weekends, so it merely adds the exact number of days specified. As such, if you are counting only business days, you would need to account for weekends and holidays manually. Additionally, only positive whole numbers are accepted for the number of days to add.
