When Does The All Access Pass Coupon Expire That Was Sent At The End Of April?

i’ve had the all access pass for years, and i’ve always received my coupons in the mail… but this time, the coupon got lost in the mail. so i called them, and they put a note on my account that i could use for my coupon. the problem is that i don’t know when the coupon for this earning period expires. i know they expire typically “one month” after they’re mailed, but i need the actual date that is printed on the pass as its expiration. i don’t have the actual coupon, so i can’t look at it myself.
