A Pokemon event can refer to different things. An official tournament can count as an official Pokemon event but more often it refers to a distribution of a (usually) rare Pokemon. This distribution can happen over WiFi or is held at a certain location where you can download it.
A Pokemon event is a once in a while event. Nintendo has an online event in which a person may receive special downloads or additional pokemon. This happens in both America and Japan.
It's where you go somewhere in real life, bringing your game and handheld system with you, and after unlocking mystery gift in the game, you can receive Pokemon and items that you couldn't normally get, such as ARCEUS and DARKRAI (wooT!) and all those kinda awesomeness Pokemon :D
There no pokemon event

as long as the event is still going on, there is a way. it involves getting the same "event gift" in Pokemon diamond/pearl and trading to Pokemon platinum.
