if so, why? if not, what would be a better alternative?
sometimes i've wished it could be 10 days, but it's much harder for it to feel valid, because the rest of the world is so hooked on to the 7 day. All our devices tell us where we are in the 7 day. And adhering to that has a validity that you just can't get with another value. However, i do think it's good to rotate it and have the start time be different, so that way i feel like it's my own, and is also not subject to random monday holidays
