How Age Is Calculated

The calculator compares two calendar dates and calculates the exact difference in years, months, and days. Unlike simple year subtraction, the calculation automatically accounts for leap years, different month lengths, calendar rules, and exact dates. This provides a much more accurate result than estimating manually.

• Double-check both dates before calculating.
• Use today's date for your current age.
• Choose any past or future date to calculate a specific time difference.
• Remember that leap years are included automatically.
