if it is a nationally televised game usually at the kick/tip/drop of puck/1st pitch. if it is a game than the "starting" time of the game. ie 4pm even though it really starts a few min later. but sportsbooks dont have access to all the games on tv. specially if overseas. usually football is open all week. have plenty of time to make the wager if you want to. gotta know your book and when they pull it down. can usually call in and maybe ask the manager to add more time if the game is in a delay.
