Same time as on any night - shortly after sunset during astronomical twilight. Movies start latest on June 21st, and gradually start earlier on either side of that date towards spring or fall. The day of the week only impacts when the box office opens. 7:30 on weekdays (Sunday/Thursday) 7:00 on weekends (Friday/Saturday)
Around 9:30-10pm
Sunset, so varies during the months it's open.
