1. What is Date Addition?

Date addition is the process of calculating a future or past date by adding or subtracting a specific time period (in this case, 6 months) from a given date. This is commonly used in financial calculations, project planning, and medical follow-ups.

The calculator uses PHP's DateTime functions to accurately add 6 months to your input date:

The calculation handles:
