Present Perfect Tense
You use the present perfect tense to express completed experiences, accomplishments, and changes that have occurred before the present moment. You also use this tense to express uncompleted actions that you expect to finish or to describe multiple actions that occurred at different times.

In order to use the present perfect tense correctly, you must refer to actions or states of being that have taken place over an indefinite period of time, not one time events. For a specific or one-time event occurring in the past, you use the simple past tense.
For instance, if you say, “I have been on a cruise ship,” the present perfect tense, you simply mean that you have had this experience. Contrast that statement with this one in the simple past: “I went on a cruise to the Bahamas in February, 2002.”
