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.
how do you get arceus whit cheats in Pokemon heartgold
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.
No, you have to get arceus either from an event or from a gameshark cheat :(

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.
