When does a person attain a specified age for legal purposes?

• A. On the day of the birthdate
• B. On the next birthday after birth
• C. On the anniversary of the birthdate
• D. On the day of the anniversary of his birthdate

Answer: (C)

Age for legal purposes is reached on the annual birthday—the anniversary of birth. You start life at age zero, and you reach any given age on your birthday each year. So turning a specified age happens on that birthday, not on the day you were born or earlier.

The day of birth is birth itself, not the moment you attain a higher age. The next birthday after birth would be age one, not the higher age in question. The key idea is the yearly anniversary of the birthdate.
