Since when, till when

[tufguy]

Hello guys,

I have come with a new question, Can we say "since when till when" is this correct? or do we have to say "Since when to what date" or "From when till what date", like if i want to say "i want to know he remained active since when till when" or since when to till what date".

Usually "since" is used to denote a span of time from the past to the present. He has been unemployed since November, 2013. When we want to talk about a span of time in the past, we use "from". He was unemployed from May through July.

He was unemployed from May through July.

I agree with Mike, but in BE we say '...from May to July'.

Can we say "since when till when"?

No, but we can say 'from when till when?'

A: 'I used to work for Perry Scoap, the optical instrument maker.'

B: 'Did you? From when till when?'

A: 'From May, 2003 till April, 2004.'

If you are asking the question because you want to know the dates, then you can say "…from when till/to when?".
I say "till/to" because I believe either is acceptable.

A: He taught at our school for a few weeks last year.
B: From when till when?
A: From the middle of March to the end of April.

P.S. Sorry for the duplication, Rover. For some reason your edit wasn't there when I posted. I'll leave it up for the "to" option.
