What is the difference between “till” and “until”?
Please kindly advise me on the correct usage of till/until when talking about period of time. For example:
This offer is valid from Apr 21st until/till Apr 28th.
Also, I would be grateful if you could tell me what variants are possible if I want to squeeze this phrase into a small area? How can I make it shorter? That is, what parts can be omitted? The suffixes (st, th)? For example:
Apr 21 - 28
