2 For and since are often used with the present perfect. When talking about an action's duration<br />
we use for if we talk about the period of time, and since if we say when the action began.<br />
e.g. for six years, for a long time, for more than an hour.<br />
since 2001, since January, since he joined the company.<br />
Other time expressions typically associated with the present perfect are:<br />
ever, never; just, already, yet; in the last few days / months etc., all day, all week, all my life<br />
etc., how long, once, twice, several times, etc.<br />
Many of the above expressions can also be used with the past simple, if they refer to a<br />
completed period of time:<br />
We’ve made a lot of money this first quarter. (Said in March - the first quarter of the year hasn't<br />
finished.)<br />
We made a lot of money this first quarter. (Said in April or later - the first quarter is complete.)<br />

However, if we go on to give more specific information about the subject and start talking about<br />
a specific date, we have to use the past simple.<br />
