1. What is Date Addition?

Date addition is the process of calculating a future or past date by adding or subtracting a specific number of days from a given start date. This calculator focuses on adding days to a date.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Date \) — The starting date
• \( Days \) — Number of days to add (positive integer)
• \( NewDate \) — The resulting date after addition

Explanation: The calculation accounts for varying month lengths and leap years when adding days to a date.
