The short answer
Acontecer is a common way to ask what happened, describe an event, or explain that something unexpected took place. The subject is the event or situation, not usually the person who caused it.
Use acontecer for everyday events and surprises
For a quick question, O que aconteceu? is a natural phrase to learn as a complete expression.
O que aconteceu ontem?
What happened yesterday?
A reunião aconteceu no auditório.
The meeting took place in the auditorium.
Isso nunca tinha acontecido comigo.
That had never happened to me.
Use ocorrer when the tone is more formal or report-like
Ocorrer can also mean to happen or take place, and it often appears in notices, reports, and more formal explanations. It is useful when describing an event, delay, or problem in a structured message.
The verbs overlap in many sentences. For relaxed conversation, acontecer is a useful default; for a formal report, ocorrer may fit the tone.
O evento ocorrerá no sábado.
The event will take place on Saturday.
Houve um erro durante o pagamento.
There was an error during payment.
A palestra vai acontecer na sala principal.
The talk will take place in the main room.
