You can't get it now. It already passed, the only hope for you to get it is by using the Action Replay and get the code for the event.
A celebi event has already passed. The celebi event for HeartGold was available in Japan at the release of the game. There isn't an event for celebi going on right now.
You do not get Celebi anywhere in HeartGold. The only ways you can get a Celebi is by downloading an available Nintendo event where it is offered however there wouldn't be anymore events for HeartGold or you can trade with someone else who was able to get a Celebi at an event.
Celebi
The Celebi event for HeartGold and SoulSilver has already came and went. It started on February 21, 2011 but it ended on March 7, 2011. There is no chance of the Celebi event download for HeartGold and SoulSilver repeating so the only way you can get the event Celebi is by trading for it.
you can only get celebi in an event or pal park.
Yep
You can only find celebi in the special event.
You need to have the Celebi event. it is over. sorry
you can't! you have to get the special event celebi or use AR
No, it is not possible to do the event in HeartGold and SoulSilver with any Celebi because the game reads what is encoded in Celebi's summary. You need a Celebi with a "Fateful Encounter" flag on it (this flag will be shown in its summary) in order to unlock the event in HeartGold and SoulSilver.
there is going to be an event for celebi later on. go to www. serebii .com to find more about it.
