Taking the Pill at the same time

Sorry if this seems like a dumb question, but I’m super forgetful and my schedule changes daily. I take the 3 week active, 1 week placebo pill which is supposed to be taken at the same time every day. While I am consistent in taking the pill, the time I take it fluctuates (never by more than 2-3 hours max). Will this make my BC ineffective, and if so does anybody have a time they find is the easiest to take the pill.
