Understanding Lunar Age Systems
Chinese Lunar Age System
The Chinese lunar age system is fundamentally different from the Western age calculation. In Chinese tradition, a person is considered one year old at birth, accounting for the approximately nine months spent in the womb.
Key Principles:
- •Age increases at Chinese New Year, not on birthday
- •Born as 1 year old (womb time counted)
- •New Year date varies (January-February)
- •Still used for traditional celebrations
Hijri Lunar Calendar
The Hijri calendar is a purely lunar calendar used in Islamic countries. It was established in 622 CE and consists of 12 lunar months, making it about 10-11 days shorter than the solar year.
Key Features:
- •354-355 days per year (lunar year)
- •Used for Islamic religious observances
- •Ramadan, Eid dates determined by this calendar
- •Gradually shifts relative to solar calendar
Conversion Factor: The 0.027 factor accounts for the gradual accumulation of the ~10-day annual difference between lunar and solar calendars.
