How to Say "Date of Birth" in Chinese

出生日期

chūshēng rìqī

The Chinese phrase for "date of birth" is 出生日期 (chūshēng rìqī).

出生日期 is the standard term used on official documents, forms and applications.

Meaning: date and year when something was born (noun)

What does it mean word for word?

The term is composed of 出生 (chūshēng), meaning "to be born" and 日期 (rìqī), meaning "date".

While 出生日期 refers to the specific calendar date of birth for documentation, 生日 (shēngrì) is used for the annual celebration of one's birthday.

chūshēng rìqī

In Chinese culture, the concept of 'age' can be counted in two ways: the actual age since the 出生日期 and the traditional 'nominal age' where a baby is considered one year old at birth.
In historical Chinese records, a person's 出生日期 might be recorded using the sexagenary cycle, which names years based on a 60-year combination of heavenly stems and earthly branches.
The character 出 in 出生日期 literally means 'to go out' or 'to exit', framing birth as the act of exiting the womb.
