five and a half 21:30 - 16:00 = 05:30
11pm 11pm in December (holiday hours) but regularly Monday-Satuday: 930pm Sunday at 8pm
2:30 hours from 9:30pm to midnight, then 8:30 hours from midnight to 8:30am. Total is 2:30 + 8:30 = 11:00 so answer is 11 hours. Alternatively 9:30pm to 9:30am is 12 hours, then minus 1 hour to get to 8:30am, so 12 - 1 = 11 also.
Just put 21.30 because if you use large and small it makes you look a nerd.
Depends on the time of year: Hours are as follows: January - March 10am - 830pm April - June 10am - 9pm July - August 10am - 930pm September - December 10am - 830pm
