I called the theatre and asked them this very question and the worker in the other end told me that they open up about 20 minutes prior to the first show of the day so tomorrow they will open up at 10:20am since the first show starts at 10:40am. You can check the moviefone app for the earliest show times at this or any other theatre on your computer or on your smartphone.
It depends on the day of the week. Weekdays the first Showtime is around 11-12. Weekends the movies start around 9am. Fandango shows all their movie times. Seats are reserved so I highly suggest buying early or online. There's been times when if you didn't buy tickets the day before they were sold out.
2 pm to 11 pm
