To Ricardo and all the people who - myself included - think that prepositions suck! 

                           1- AT

  I have to wake up tomorrow at 6:00

Note: Activity + AT ..........but

Saying the time: No Preposition

EX: We're going to be late! The movie starts at 8:00 and it's 7:45 now.

 At the zoo, at the restaurant, at the theater, at the supermarket, etc.

 Exceptions:

 At church, at home, at work, at school (without THE)
