Celebi was an event during 2011 in Pokemon Soul Silver, Heart Gold, Pearl, Diamond, Platnium. But now it already passed. Maybe they'll get an event for Celebi for Pokemon Black and White. You can also use the Action Replay and get the code for Celebi.
Im sorry to say but you can not catch the legenedry celebi in Pokemon heart gold but you can get action replay and type in the code for action replay to catch celebi or you could go to the next celebi event
you find out in the celebi event, but it deals with Giovanni.
To get celebi, there is an event that has only been realeased in japan
