The Simplest Guide to Calculate Lunar Age

Basic Formula

Lunar Age = Current Year (lunar) - Birth Year (lunar) + 1

Important note: You must convert both the current year and birth year to lunar calendar before calculating.

Specific Example

Let's say you were born in 1995 (Year of the Pig) and it's currently 2025 (Year of the Snake):

  • Lunar age = 2025 - 1995 + 1 = 31 years old

However, if your lunar birthday hasn't passed yet this year, subtract 1.

Special Cases When Calculating Lunar Age

Born in the 12th lunar month: Some people born at the end of the lunar year but beginning of the solar year (January-February) should note:

  • The lunar birth year might differ from the solar birth year
  • Example: Born January 15, 1995 (solar) might be December 1994 (lunar)

How to Look Up Lunar Year Names

Understanding the Stem-Branch System

To master calculating lunar age, you need to understand the year-naming system. Each lunar year is named according to the stem-branch system consisting of 10 stems and 12 branches, creating a 60-year cycle.

10 Stems: Giáp, Ất, Bính, Đinh, Mậu, Kỷ, Canh, Tân, Nhâm, Quý

12 Branches: Tý, Sửu, Dần, Mão, Thìn, Tỵ, Ngọ, Mùi, Thân, Dậu, Tuất, Hợi

Combining 10 stems and 12 branches creates a 60-year cycle. For example: 2025 is the Year of Ất Tỵ (Year of the Snake).

Date Differences

Lunar and solar calendars can differ by 1-2 months. Key points to remember:

  • Tet (New Year) usually falls in January-February of the solar calendar
  • Some years have 13 lunar months (leap years)
  • The leap month is added in the middle of the year

Common Mistakes

Birth year confusion: Many people born at the end of the solar year but beginning of lunar year

Ignoring birthday dates: Age doesn't increase until after the lunar birthday
