In Pokémon Diamond/Pearl/Platinum there are events that you can only participate in once a day or once a week. These events are usually minor things like bringing an NPC a certain item, or a certain Pokémon appearing.
Daily Events
Jublife TV Lottery
In Jubilife City, at the TV station, you may participate in a daily lottery. The lottery uses the trainer ID of any of your Pokémon as a ticket number.

The prizes that may be won are as follows.
