When you get cremated, the coffin goes up in smoke too, and you still need one for the service.

I would imagine that the coffin maker sells his wares to funeral homes, so the calendar is for people already in the industry. Probably not intended for the end user at all, unless you happen to be one of those freaky people who like to plan out their funeral way ahead of time (like my recently passed grandmother-in-law).
