Indians often mix "since" and "for". The rule is simple once you see it.
Use "since" with a point in time
- since Monday
- since 2020
- since morning
- since I was a child
"Since" answers the question "from when?"
Use "for" with a duration
- for two days
- for three years
- for an hour
- for a long time
"For" answers "how long?"
Examples
- I have lived here since 2021.
- I have lived here for five years.
Both are correct but mean slightly different focus.
Quick test
If you can put a clock or date after it, use "since". If you can count the time, use "for".
Common error
Wrong: "I am waiting since two hours." Right: "I have been waiting for two hours."
