|Occurs||2nd Saturday on every odd-number month|
La-Di-Day is an event in Wild World that occurs every second Saturday of every odd-number month. Villagers participate in a competition for a new Town Tune. The only villagers who do not participate are those who are sick, moving in, or moving out.
Villagers will sing their song to the player and will try to impress the player with their tune. The player may go to every animal in their town and find the tune they find most pleasing. Tunes that the player would like to be made the new town tune must be responded to with "You're hired!", and the tunes that the player does not want must be responded to with "That won't do". Villagers may become slightly upset (or angry) if the player doesn't pick their song, but having their contribution rejected seems to make them determined to do improve. The contribution of the last villager to whom the player says "You're hired" will become the new town tune. The tune will sound different when played as the town tune than during its playback earlier in the event. The more the player says "That won't do" the more determination villagers will put forth. If the player says "That won't do" to a villager's song, that song will not be played again.
