Both forms are grammatically correct (contrary to what some British grammar purists claim). The first (“What happened?”) is the one most of us would probably ever need in real life. Use “tat” when we knew something happened but want more details.
Explanation: The past tense “happened” is correct.
“When did it happen?” is incorrect because after an auxiliary verb you must use the base form of the main verb. You used “passed” which is the past tense and past participle of “happened”. The correct wording would be “When did it happen?“
You don’t know if something happened, so you ask if something happened. What happened? = You know something happened, but you don’t know what, so you ask what happened. See a translation.
“What happened” is the past tense of “what happened”. It means something started in the past and ended in the past. “Happened” means that something started in the past and has just ended. “happened” is Simple Past and indicates a specific time or moment in the past.
Happen’s past is happened.
“When did the policy become more important than the actual US citizen?” ask her. When did it happen that you had to defend a good wage?” Big Labor has fewer friends in high places. Then we say, “Well, when did it happen?” It could have happened two, six, eight years ago and we didn’t know…
“Why did this happen?” is asking for reasons and maybe an attempt to find some kind of meaning for the event. Answers could be “It happened because God/Allah/etc. wanted it that way”, or “it happened because the stars are aligned that way”, or even “there is no reason, it just happened”.

Happen, which originally meant the accidental or accidental, is now the most general word for occurring: Something happened. p>
happened – it means that something happened and is still happening today. For example, “Mercedes has been making cars for a long time.” They still make cars, so you need a past tense with “have” here. Happened – it means something happened before something else happened.
They are all correct in context, although you don’t need the comma. I wanted to see what would happen if the fuse blew. Here you describe an action in the past that is not completed. I wanted to see what would have happened if the fuse had been lit.
It is wrong because happened, since the perfect tense indicates a temporary or at least completed action; while for a while now indicates something enduring and requires imperfect tense. So it happened a while ago or it’s been happening for a while now but not? It’s been happening for a while now.
