However, there are a few ways to think about this:
* Release Date: The movie premiered on December 21, 1937, so you could consider that its "birthday."
* Anniversary: You could celebrate the anniversary of the movie's release every year on December 21st.
* Fictional Birthdays: Fans have created fan-made birthdays for Snow White and the dwarfs based on their characters and the movie's events. But these are not official.
So, it depends on how you want to think about it! 😊
