1. What Is Age Calculation?

The age calculator determines a person's exact age in years and months based on their birth date and a current date. The special calculation for 59½ years old is particularly important for retirement account withdrawals in the United States.

2. How Does the Calculator Work?

The calculator uses the following calculation:

Where:

• \( Current\ Date \) — The date to calculate age as of
• \( Birth\ Date \) — The person's date of birth
• \( 714\ Months \) — Equivalent to 59.5 years (59 × 12 + 6)

Explanation: The calculation accounts for the exact number of months between two dates to determine if someone has reached the important 59½ year threshold.

3. Importance of Age Calculation
