Long rest, only has benefit every 24 hours, does that mean every 2 days?

@TheImmortalDMChief! Long rest, only has benefit every 24 hours.. Does that mean every 2 days? Ie. Rest 10pm-6am, need to wait til 6am? nope, 24 hours is based on when you get the benefits, not when you start. hitting at exactly 24 is fine

@TheImmortalDM realistically, anything 20+ hours works, just awkward to write rule that way
