How to Calculate Your Age from a Birthdate

Step-by-Step Age Calculation

Here’s a simple method to calculate your exact age:

1. Calculate Years: Subtract your birth year from the current year.
2. Adjust for Months: If the current month is earlier than your birth month, you haven'tcompleted the current year of your life yet, so subtract one from the year count.
3. Adjust for Days: If the current month is the same as your birth month, but the current day is earlier than your birthday, you also haven't completed the current year. Subtract one from the year count.
4. Calculate Months and Days: For a more precise age in years, months, and days, specialized date-difference logic is needed to handle the varying number of days in months.

Example:

If the current date is October 26, 2024 and your birthday is December 5, 1990:

• Years: 2024 - 1990 = 34 years.
• Months Check: October (10) is earlier than December (12), so you are not yet 34. Your age is 33.
