What is Age?
Age is the length of time that a person, animal, object, or entity has lived or existed, measured from a specific starting point, usually the date of birth or creation. It is typically expressed in years, but it can also be measured more precisely in months, weeks, or days.
Age plays a critical role in various fields, including education, health care, law, and even entertainment. From calculating eligibility for school admissions and job applications to determining retirement or insurance benefits, accurate age information is essential.
