Hi Whistler, and welcome to the forum! On previous occasions of similar offers, in which a date was printed on the Swiss Pass, this turned out to be the date at which the validity of the pass should start at the latest. In that case, 31st May wouldn't be the end date of your pass, but only the date at which you should have started using it. So there wouldn't be a problem then and your Swiss Pass would be valid in 1st class on all 8 days.
But I'm not sure of this, as I don't know exactly what's printed on your pass and what the exact rules of your offer are. Your travel agent should be able to help you out on this. If you could let me know exactly what's stated on your pass and how it's said, or better: scan it and post it here as an attachment, I could probably be of better assistance. Could you try and give some additional information? Thank you!
