Suppose you were born on May 05, 1990:

Your actual age (years) = 2024 - 1990

Your actual age (years) = 34 years

Let's compare it with the Chinese calendar!

  • For the lunar calendar 2023, this date falls on January 22
  • The lunar calendar 2024 falls on February 10

Lunar age = 34 +1 = 35 years
