According to the man page, neither of these will not do what the OP wants. Both will execute the command EVERY Saturday. The first will also execute it on the 8th and 22nd of the month. The second will execute the command TWICE a day AND days 8-14 AND 22-28. The man pages says if any of the day parameters match, the command is executed. Unfortunately for the OP, the day parameters are an OR operation and not an AND operation.
