there are options. Option 1 mystery gift option 2 action replay online codes and option 3 event
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 :(
you cant,there are no more darkrai events in America
By Event or buy Action Replay
you either trade or do the arceus event
Trade from Pearl or HeartGold/SoulSilver (Arceus event)
No, unfortunately, you can't. Unless you use a game shark or action replay. To get Arceus, you have to do a Pokemon special event such as the 12th movie Arceus event. There are rumors that there will eventually be other Arceus event as well.
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.
You use it to get a baby Palkia, Dialga, or Giratina in an event in HeartGold/SoulSilver
There is an event where you can get it from.
in HeartGold + SoulSilver, it is the mew event, then the celebi event, then enigma stone for latios/latias.
