Birth date and age calculation method
Winkler was born on May 30, 1945. Happy Days premiered on January 15, 1974, making him 28 years, 7 months old at the time. For each subsequent season, age was calculated by comparing the episode's original airdate to his birthdate. No birthdays occurred between May 30 and series airdates within seasons, so ages advance by one only after May 30 of each year. This approach aligns production records with broadcast dates to ensure precision.
