Once daily does the trick if you are willing to push it each week.
Other than that, I'd fully recommend picking a room in your house and every time you enter it you do a set of the push ups that you are doing today. Combine that with the routine and you get a much smoother transition between weeks, especially when you start getting up in numbers.
For example,
Lets say you are doing 6 sets of 8 push ups and you choose your bedroom. Every time you enter your bedroom, you do 8 push ups. A long with that, you also do you 6 sets of 8 at the end of the day.
