Goal
You’ll be able to talk about past experiences using present perfect correctly for this specific purpose, and know the genuinely important distinction between describing an experience and describing a specific completed event.
Learn
When talking about life experiences — things you have or haven’t done at any point in your life, without specifying exactly when — English uses present perfect: have/has + past participle:
I have visited Paris. (at some point in my life, unspecified when) She has never eaten sushi. (never, at any point in her life) Have you ever tried skiing? (asking about life experience)
The genuinely important distinction: if you mention a specific time, you must switch to simple past instead — I have visited Paris (experience, unspecified time) versus I visited Paris last year (specific past event, specific time mentioned). Mixing these incorrectly — I have visited Paris last year — is a genuinely common mistake, combining present perfect with a specific time reference that requires simple past instead.
Common present perfect experience markers: ever, never, before — Have you ever been to Japan?, I’ve never tried that., I’ve done this before.
Decision Task
You want to say you visited Paris specifically last year, mentioning the specific time. Before reading on: would you say I have visited Paris last year or I visited Paris last year?
Show Answer
I visited Paris last year. — since you’re mentioning a specific time (“last year”), simple past is required, not present perfect. I have visited Paris last year is a genuinely common mistake, incorrectly combining present perfect with a specific time reference.
Common Mistake
Using present perfect together with a specific time reference (like “last year,” “in 2020,” “yesterday”), producing an incorrect combination. Present perfect is specifically for experiences without a specified time; the moment you mention a specific time, simple past is required instead.

Try It Yourself
Without looking back, write one sentence using present perfect for a general life experience, and one sentence using simple past for a specific past event, both about the same general topic (like travel or food).

For example: I have traveled to many countries. I traveled to France in 2019. — present perfect for the general experience, simple past for the specific, dated event.
