You don't even need to do KY daily. You can do it a few times a week and still make progress. There is absolutely no need to do it daily, unless it's a specific kriya you are trying to get benefits from, and even then there's flexible room.
This is important: unless you are actively working with the Gods on raising your Serpent (and there will be NO DOUBT whatsoever about this), you do not have to worry about timings for KY. You can relax and have a more chill attitude. Do it when you want.
