What is the difference between chronological and biological age?
Chronological age is simply the amount of time that has passed since your birth. Biological age represents how fast your body is aging based on biomarkers, lifestyle, and genetics.
How to calculate age from date of birth manually?
To calculate, subtract your birth year from the current year. Then compare the current month and day to your birth month and day; if your birthday hasn't occurred yet this year, subtract one from the year count.
