5. Frequently Asked Questions (FAQ)

Q1: How does it handle months with different lengths?
A: The calculator automatically adjusts for varying month lengths. If the resulting date would be invalid (e.g., August 31 + 6 months = February 31), it returns the last valid day of the month (February 28 or 29).

Q2: Does it account for leap years?
A: Yes, the calculation properly handles leap years when adding months that include February.

Q3: Can I calculate dates other than 6 months?
A: This specific calculator only calculates 6 months ahead. For other time periods, you would need a different calculator.

Q4: What's the maximum date range it can handle?
A: The calculator can handle dates from year 1 to year 9999, as supported by PHP's DateTime functions.

Q5: Is the calculation timezone-aware?
A: The calculation uses the date only without time components, so timezones don't affect the result.
