Using the Present Perfect Tense: FOR or SINCE? We use Present Perfect tense to talk about action which started in the past and continues up to the present. Examples

I have had this computer for about a year.

How long have you been at this school?

I haven't seen Julia since September.

Tip! For other uses of the Present Perfect tense, see the Present Perfect Tense - When To Use. We use for with a period of time, for example: a few days, half an hour, two years. We use since with the time when the action started, for example: last year, June 8, I met you. Each of these present perfect sentences contains a time expression. Each time expression is a length of time (which requires FOR) or a starting time (which requires SINCE). 1 Maya has been a professional ________ 1989.
