The alcoholic calendar

I was just thinking about how I would mark time as a drinker. Any time I had anything scheduled, particularly if it was something I was not looking forward to, I would calculate how many times I could get drunk before doing it.

I think of it now like an anthropologist studying a distant civilization and their calendar system. But, instead of marking phases of the moon or whatever, all planning and scheduling was predicated on how many times I could get drunk between now and then.
