When we use the Present Perfect it means that something has happened at some point in our lives before now. Remember, the exact time the action happened is not important.

Sometimes, we want to limit the time we are looking in for an experience. We can do this with expressions such as: in the last week, in the last year, this week, this month, so far, up to now, etc.

Examples:

* Have you been to Mexico in the last year?
* I have seen that movie six times in the last month.
* They have had three tests in the last week.
* She graduated from university less than three years ago. She has worked for three different companies so far.
* My car has broken down three times this week.
