Bovine females do not have their "periods" like human females do. The "period" is a loose or code term for when the endometrium layer is shedding and the girl or woman is experience heavy bleeding from the uterus through the vaginal opening. Cows nor heifers experience none of this. They have a sexual receptive period called Estrus where they experience high estrogen levels that drive them to search for and find a bull to breed with. Human females do not have a defined sexual receptivity period, so all their reproductive cycling is denoted by the timing of their periods. Depending on the breed, the average age for a heifer to experience her first estrus period is between 13 and 18 months of age. See the related questions below for more information.
