Main Features of the Date Calculator
This date calculator provides two main functions:
- Calculate Date Difference: Calculates the number of days between two dates. By default, it subtracts the start date from the end date. If the "Include Start Date" option is selected, the start date will be counted as day 1.
- Add/Subtract Days from a Date: Adds or subtracts a specified number of days to/from a specific date to calculate a new date. If the "Include Start Date" option is selected, the selected date will be counted as day 1.
Explanation of the Include Start Date Option
If the "Include Start Date" option is set to "Yes", the start date will be counted as day 1. For example, to calculate the days between February 16, 2025, and February 17, 2025:
- "Include Start Date" = No → Result: 1 day
- "Include Start Date" = Yes → Result: 2 days
Similarly, when adding or subtracting days, selecting the "Include Start Date" option will count the specified date as day 1.
For example, if 1 day is added on February 16, 2025:
- "Include Start Date" = No → Result: February 17, 2025
- "Include Start Date" = Yes → Result: February 16, 2025
