Despite the name, there are three main schedules for this community:
Mood prompt posting will begin on January 1st and continue through the year. The Maximum track will include all 132 moods; the Minimum Track will include the bare minimum 15 moods for a complete mood theme, plus an optional three moods that will give you the greatest image variety in your mood theme for the fewest actual images; the Medium Track includes all 34 higher-level moods that other moods inherit images from.
Roughly three of Dreamwidth's "moods" will be prompted each week for each track. The Maximum and Medium Tracks have a week-long break scheduled every seventh week. These breaks can be used to catch up on moods you missed, re-do moods you're not satisfied with, get a head start on future moods, work on uploading your custom mood theme, or really to just take a break. Rest is important too, after all!
Additionally, the prompted moods are just suggestions; you can work on the moods in any order you wish. While the order of all tracks is based on the mood hierarchy tree, starting with the mandatory moods and then moving on to the mid-level "branch" moods, participants are welcome to join in or leave at any time. Anyone looking for a particular challenge is welcome to check out the Mood Theme in a Month calendars, with a goal of completing at least one mood image per day to cover all of the Medium Moods! Or, if Bingo is more your style, here's a couple of Bingo cards to cover either all the Minimum Moods plus one, or most of the Medium Moods.
