Difference between till and until?

Please explain difference between till and until with examples.

We have explained this often here on the forum. Here is just one of the many threads: till vs until (If you want till/untill tomorrow it will be too late)

then please explain the word “till” with examples.

Have you tried finding examples in a Learner’s Dictionary, Debashis. Looking for yourself will help you become an independent learner.

yes ,I tried . But I get often confused between “till” and “unless”. Also previously I thought that “until” is antonym of “till”.

what I think about “till” is that it describes some point on the time axis . But What my confusion is like following:

We’re open till 6 o’clock.(the sentence is taken from that dictionary.)
Now can’t I say
We’re open unless the time is 6 o’clock.

That doesn’t work, but you can say ‘we’re open until 6 o’clock’, because you are correct about ‘until’ and ‘till’ being antonyms. Did you see this footnote on the dictionary page:
“Till is generally felt to be more informal than until and is used much less often in writing. At the beginning of a sentence, until is usually used.”

‘Unless’ cannot be used in place of ‘until’/‘till’
In your example it indicates that if the time is, for example, five past six, then they are open. It is only at exactly 6 o’clock that they are closed.
Unless:
