[h=1]For and Since for Time[/h] We often use for and since when talking about time.
for + period
A period is a duration of time, for example: 5 minutes, 2 weeks, 6 years. For means "from the beginning of the period until the end of the period." For can be used with all tenses.
since + point
A point is a precise moment in time, for example: 9 o'clock, 1st January, Monday. Since means "from a point in the past until now." Since is normally used with perfect tenses.
For can be used with all tenses. Here are a few examples:
Both for and since also have other meanings, with no reference to time. Here are some examples:
