How to Calculate Birth Year for 17 Year old
To calculate the year someone who is 17 year old was born in, you can follow these steps:
Determine the current year: Find out the current year, which is the year in which you are performing the calculation.
Subtract 17 from the current year: Since the person is 17 year old, you need to subtract 17 from the current year to find the year of their birth.
Account for the birthdate: If the person has already had their birthday this year, the year of their birth will be the same as the result of step 2. If their birthday is later in the year, subtract 1 from the result of step 2 to account for the fact that they were born in the previous year.
The formula to calculate the birth year for a 17 year old is:
Current year - 17 (if their birthday has already passed)
OR
Current year - 17 - 1 (if their birthday is later in the year)
