it's twp years or it's been two years?

[emsr2d2]

But you can't use it with present/past continuous,can you?
Eg.: It is/was raining since Tuesday. (This is incorrect, isn't it?)

You're right. Those are not possible.

Present Tense: She stays here since childhood.
Present Tense: She plays tense since she was young.
Are these sentences correct?

[5jj]

No

[keen learner]

No

I'm little confused here...

Does it mean you can't use "since" in "simple present" and "past present" or can you use them in some specific constructions?
If you can then please explain how and when?
Thanks

I meant "simple past".

With states or activities extending from an earlier time point/period or action, we normally use a perfect aspect, as you can see in emsr2d2's examples:

Present perfect: I have been on a diet since Monday.
Past perfect: I had been on a diet since the preceding Tuesday.
Present perfect continuous: I have been dieting since Monday.
Past perfect continuous: I had been dieting since the preceding Tuesday.

and mine:

I have been on a diet since I met Fifi.

However in constructions with it + BE + time period, we can use either a non-perfect or a perfect form:

1) It's two years since I went on holiday.
2) It's been two years since I went on holiday.

Yes, it's incorrect there. But it's OK with present or past perfect continuous:

It has been raining since we arrived.
The said it had been raining since they arrived.
I have been trying to get a straight answer since last year...

Thank you.


It's one week since I played tense.
It was one week since I had played tense.

Are these sentences correct as per the rule you stated in your post?
("However in constructions with it + BE + time period, we can use either a non-perfect or a perfect form:")

[keen learner]

I meant "tennis".

[5jj]

I didn't say it was a rule. I said it was what we can do. Your sentences are therefore possible, although unless I wished to place emphasis on the number 'one', I'd be more likely to say 'a week'.
