1. What Is Date And Month Calculation?

Date And Month Calculation is a method to determine the total number of months between two dates. It calculates the difference in years and months to provide an accurate duration measurement in months.

2. How Does The Calculator Work?

The calculator uses the Date And Month Calculation formula:

\[ \text{Months} = (\text{End Year} - \text{Start Year}) \times 12 + (\text{End Month} - \text{Start Month}) \]

Where:

\( \text{Start Year} \) — Beginning year of the period
\( \text{Start Month} \) — Beginning month of the period (1-12)
\( \text{End Year} \) — Ending year of the period
\( \text{End Month} \) — Ending month of the period (1-12)

Explanation: The formula converts year differences to months and adds the month differences to get the total duration in months.
