How It Works

The Age Calculator determines the time difference between two dates:

  • Calculates years, months, and days between dates
  • Handles month and year rollovers correctly
  • Accounts for leap years
  • Provides precise age calculation

Detailed Explanation:

This calculator uses a sophisticated algorithm to determine the exact time difference between two dates:

Basic Calculation:

  • Years = End Date Year - Start Date Year
  • Months = End Date Month - Start Date Month
  • Days = End Date Day - Start Date Day

Month Rollover:

If the end date day is less than the start date day, the calculator:

  • Subtracts 1 from the month count
  • Adds the appropriate number of days from the previous month
  • For example: From Jan 31 to Mar 15 = 1 month and 15 days (not 1 month and -16 days)

Year Rollover:

If the end date month is less than the start date month, the calculator:

  • Subtracts 1 from the year count
  • Adds 12 to the month count
  • For example: From Jan 2020 to Mar 2021 = 1 year and 2 months

Leap Year Handling:

The calculator accounts for leap years when calculating the number of days between dates, ensuring accurate results even when the date range includes February 29th.

This calculator also includes text-to-speech functionality to announce your calculated age, making it more accessible for all users.
