I counted days for the first year, because the outpatient support group I went to every week liked to go 'round the room starting with number of days clean and sober, but after a year I stopped bothering. I remember my sober date (within a couple days, it's foggy....), and web calculators can tell me how many days it's been if I want to count, but otherwise it's "nearly 5 years" and that's close enough. Maybe in 20 years I won't remember how many years it's been, but for me it's hard not to remember such a life-changing period as a clear demarkation, before = probably drunk and after = stone sober.
