How to Calculate Age in Years, Months, and Days?

[willey4983]

I'm working on a project that requires calculating the exact age of individuals in years, months, and days. I've tried a few different methods but I'm not confident that I'm doing it correctly.

Can anyone provide a reliable formula or method to accurately calculate someone's age from their birthdate to the current date? Any code examples or step-by-step explanations would be greatly appreciated! Thank you!
