The Mathematics Behind It
Age = Current Date - Date of Birth
Example: If Date of Birth is June 15, 1990, and Today is August 10, 2023:
1. Years: 2023 - 1990 = 33 years.
2. Months: August (8) - June (6) = 2 months.
3. Days: 10 - 15 = -5 days. Since days are negative, we borrow 1 month (making it 32 years, 1 month) and add the days of the previous month (July = 31 days) to the current days.
4. Result: 31 - 5 = 26 days.
Final exact age: 33 Years, 1 Month, and 26 Days.
