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.
