How Age Calculation Works Across Different Cultures

While the Western world generally calculates age starting from zero at birth and adding a year on each birthday, this is not a universal standard.

The East Asian Age Reckoning

Historically in many East Asian cultures, a person is considered one year old at birth. Furthermore, age increments occur on the Lunar New Year rather than the individual's birthday. This means a baby born just before the Lunar New Year could be considered two years old just days after birth.

Standardization

Today, for legal and medical purposes, most countries have adopted the chronological age system (starting at zero). However, traditional age reckoning is still used in cultural contexts, making age calculators a handy tool for converting between systems.
