How old are you?

That question comes with two possible answers.

Calculation Number #1 - Western Style:
Current Date – Date of Birth = Round down the Age in Years.
Example: 4/7/06 – 10/6/79 = 26 years 5 months 1 day = 26 years

Calculation Number #2 – Viet Style:
Current Year – Year of Birth = Age in Years
Example: 2006 – 1979 = 27 years

The Viet Style calculation is inevitably higher or equal to the Western Style calculation. Once the birth date is passed on the calendar, then the two calculations are the exact same.

Not until recently did Viets remember their actual date of birth rather than just the birth year. Why? Because Viet Tet New Year is considered to be everyone’s birthday.
