When you are talking about something that happened in the past, that is finished, and the time period has also finished, and we know when this thing happened, which tense do you use?*
Practise these two tenses in this week's song, an old classic by U2.
We also use it to talk about things that started in the past and continue until now, or sometime around now. I've worked here for 2 years.
We use the past simple (preterite) to talk about things that started and finished in the past. For example, I went to Cannes yesterday.
