This calculator works in two modes and allows you to calculate:

1. Calculation of days: After selecting the start and end date, the calculator will calculate the number of days between them (this function is convenient when calculating the number of days per business trip). The first day in the specified interval is also taken into account.

2. Calculating the date: Selecting the starting date and the number of days calculates the ending date (this function is convenient when calculating the date of leaving for work after the holidays). Displays the day when you need to exit.
