getting a mod to perform daily tasks - how to check current day?

[Kokolums]

Simple question - I want my mod to perform a task once a day (cleanup some variables) - What command can I use to get what day it is so I can compare it to the last time the user logged?

Very simple, create a saved variable to store the time you last did something, then check your variable on an event eg: PLAYER_ENTERED_WORLD or on exit or something.

You just want to balance how frequently you do the check. Against how likely it is you miss the window.
