for my beard, sundays, tuesdays and thursdays. i know it sounds a little strange but this is how i planned it. there are 7 days in a week so you can't go with the every other day thing and keep a weekly schedule, so i skip mondays, wednesday, and friday saturday because i have lots of time on sunday to really get a great shave so that extra days growth is nice to work with. my beard really doesn't grow that quickly so even when i did try shaving two days in a row, the irritation wasn't bad but there wasn't really any hair there. i do get a bit impatient with my beard though as i have recently started trying honing, so i really have to wait for the test shaves. i really shouldn't complain though i guess.
