When did you quit smoking? Or When have you quit smoking?

1 Answer 1


Neither is incorrect, but the first one is much more usual when asking when a past event happened.

You might use the second when talking about events in a person's whole life.

"I have tried several times to quit smoking."

"When have you [ever] tried to quit smoking?"
