2. How Does The Calculator Work?

The calculator uses the date addition formula:

Where:

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

Explanation: The calculator takes a valid starting date and adds the specified number of days to calculate the resulting date, automatically handling month transitions and leap years.

3. Importance Of Date Calculation

Details: Date calculations are essential for project planning, scheduling events, calculating deadlines, determining expiration dates, and various time-sensitive applications in business and personal life.

4. Using The Calculator

Tips: Select a valid starting date using the date picker, enter the number of days to add (must be a non-negative integer), and click calculate to get the resulting date.

5. Frequently Asked Questions (FAQ)

Q1: Can I subtract days instead of adding?
A: Yes, simply enter a negative number in the days field to subtract days from the starting date.

Q2: Does this account for leap years?
A: Yes, the calculator automatically accounts for leap years and varying month lengths in its calculations.

Q3: What date format is used?
A: The calculator uses the standard YYYY-MM-DD format for both input and output.

Q4: Is there a limit to how many days I can add?
A: While there's no strict limit, extremely large values may cause performance issues or exceed system date limitations.

Q5: Can I calculate business days only?
