There isn't a date for the Arceus Event in Pokemon HeartGold (unless you mean the event where you get Arceus). When you send over any Arceus into your HeartGold game, the event is activated. You'll have to go to the Ruins of Alph in order to do the event.

You cannot catch Palkia in HG/SS. To obtain Palkia u will need to get TRU Arceus to do the Arceus Event in the ruin of alph.
There is currently no Arceus event for Heart Gold, but there was an event for DPP where you could obtain Arceus to level 100 with the moves Spacial Rend, Roar of Time, Shadow Force, and Judgment. Currently that is the only way to legally obtain Arceus.
First, you need an Event Arceus and you go to Shinto Ruins. Cynthia will be there as well. Then Arceus can create either Giratina, Dialga or Palkia. They will be at Level 1.
You dont get Arceus in HeartGold. You need to trade one from another HeartGold or SoulSilver or trade one from the Sinnoh region games. WARNIG: IF YOU HAVE AN ARCEUS ON BLACK OR WHITE YOU CAN NOT TRADE IT BACK TO THE JOHTO OR SINNOH GAMES.

No, you have to get arceus either from an event or from a gameshark cheat :(
no you can't
Arceus is not available in HeartGold. Arceus is an event Pokemon, and cannot be found naturally in the wild. You will have to either cheat to get it, trade for it with a friend, or get it from one of your other games through Pal Park.
