That makes it sound like you're setting the YEAR et al. variables in the PROMPT_COMMAND variable. If that's the case, it's *less* wrong, but only a little bit. You still have the issue that the date might change while you're sitting at a stale shell prompt from yesterday, with stale date/time variables. Really, the fundamental problem here is that you should not be storing date/time information in long-lived variables, and then trying to use those variables at an indeterminate point in the future. Anything that needs to act upon the current date should fetch the current date immediately before acting.
