Beeminder just failed me. I failed myself too, but that’s why I use Beeminder. I found a loophole and used it.
I have a no-smoking goal set to a rate of about 1 per two weeks. I felt like smoking. I checked Beeminder. Goal is red. It’s Friday night in my timezone. I thought if I am lucky, if I enable weekends off, I will get tonight off. I tried it and the goal turned to blue.
Feature request: weekends off should apply after Arkasia horizon, so after 7 days
