出生于英语单词

I was born on 21st May,1977.我出生于1977年5月21日其他的依此类推

Date of Birth: DD/MM/YY

你是问英语单词的时候得有语境，否则一个中文意思可以对应很多英文单词，比如出生可以是名词birth，也可以是动词be born，如果是出生地就是birthplace。他出生于XX时间就是He was born in XX。

D.o.B:date of birthI was born on 月份，日（序数词），年，如：I was born on March the sixth, 1990写成：I was born on March 6th，1990
