In Spanish, the present perfect form (pretérito perfecto compuesto) refers to events that began in the past but continue or are repeated in the present, or events that have occurred recently.
The present perfect indicative formula is:
present indicative of 'haber' + past participle of verb
The auxiliary verb remains the same, an object pronoun (like 'los') that is used with the present perfect, should be placed before the word 'haber'.
