Would valid to make sense when refering to an expiration date? I've got this text right now:

Valid from: 01/10/2014
Valid to: 10/10/2014

It doesn't sound correct. Should it be until?

In which cases can I use to and not until?

    Whichever you pick, please don't use the construction found in some contest ad disclaimers: 'Offer ends October 10th or while supplies last'.

  • Why not, @JimMack?

  • Seriously? "Offer ends...while supplies last" was common (and much mocked) a few years ago, from fast food joints with promotional giveaways.

  • Didn't know that. However, why was it mocked? It makes sense to me.

  • Because it's contradictory. The offer continues or is valid while supplies last. It ends when supplies are exhausted.

Both "to" and "until" can imply that the item is not valid on the end-date specified, but only up to that date.

"Valid through" would imply that it was valid through that final end-date, and eliminates any possible misinterpretation.
