Usually the majority of us are baptized as infants or before reaching the age of reason, which the Catholic Church considers 7 years of age. There are others that get baptized older than 7 years of age and they receive their Baptism on the Easter Vigil Mass (The saturday before Easter). Usually if you were baptized after this age, you would remember receiving your baptism on the same day you also received your First Communion, and Confirmation on this same day.
