PRESENT PERFECT tense is used for past actions when the exact time is not important, but the result or experience matters now. Structure: have/has + past participle. Example: 'I have visited Paris three times.' (The exact dates don't matter - what matters is the experience). This tense connects the past with the present and is often used with 'ever', 'never', 'already', 'yet'.
