Om Puri was born in Ambala to a Punjabi family. His father worked in the railways and in the Indian Army.
As he had no birth certificate or records, his family was unsure of his
date and year of birth, however his mother told him he had been born
two days after the Hindu festival Dussehra.
When he began his schooling, his uncle chose 9 March 1950 as his
"official" birthday, however as an adult when he moved to Bombay, Puri
looked up when Dussehra was celebrated in 1950, to establish his date of
birth as 18 October
