Past Simple and Present Perfect: When to Use Each Tense

Past Simple and Present Perfect are among the topics that Russian-speaking learners often find confusing. In Russian, you can say «я сделал» and use one form in different situations. In English, it matters whether we are looking at a specific moment in the past or at the result now.

Past Simple: there is a specific past time

Past Simple is used when an action happened in the past and we mention the time:

• I watched the film yesterday.
• She called me last night.
• We visited Rome in 2024.
• He finished the task two hours ago.

Time markers: yesterday, last week, in 2024, two days ago, when I was a child.

If there is a point in the past, you almost always need Past Simple.

Present Perfect: the experience or the result now matters

Present Perfect is used when the exact time is not important, but the experience or result is:

• I have watched this film.
• She has called me.
• We have visited Rome.
• He has finished the task.

We do not say when exactly. We mean: it has already happened, and that matters now.

Compare

I lost my keys yesterday. — I lost my keys yesterday.

I have lost my keys. — I have lost my keys, and now I don't have them.

She went to London in 2022. — She went to London in 2022.

She has been to London. — She has that experience.

We finished the project on Monday. — We finished the project on Monday.

We have finished the project. — The project is ready now.

Common mistake

You cannot say: I have seen him yesterday. If there is yesterday, you need Past Simple: I saw him yesterday.

But you can say: I have seen him before. There is no exact time here, so the experience is what matters.

How to remember

Make two columns of flashcards:

Past Simple:

• yesterday;
• last year;
• in 2020;
• two days ago.

Present Perfect:

• already;
• just;
• never;
• ever;
• before;
• yet.

Then add short phrases, not just rules.

The main point

Past Simple answers the question “when in the past?”. Present Perfect answers the question “what result or experience do I have now?”. The more paired examples you repeat, the less you will want to translate directly from Russian.
