I have an instant knowledge about the number of days for some months; for the others I use the knuckle mnemonic (sped up by the fact that I remember that the two consecutive 31-day months corresponding to the index fingers are July and August.) I don’t even have to actually close fists anymore, I just do it in my mind now.
