Something occurred to me. I might be claiming one extra day by using days since my last drink as opposed to full days of sobriety completed. My last drink was on 6/25. So was yesterday 3 months or today? I would actually rather it be today as 6/25 is kids birthday. My first complete day of sobriety was 6/26. It was so long ago when I was in AA that I forget which way they do it. The last few times I quit for several months I didn't even note the starting date exactly.

EDIT - I think AA does it the way I was doing it because they call the first Day 1 and you have not completed it until midnight when they call it Day 2; there is no Day 0. I still am going to go with the 26th just to move it off the birthday.

It's one of those funky math things:

"Today makes 5 days" = "I have completed 4 days"
