Bitcoin addresses don't expire. What expires is the payment request. There is a thing called a Payment Request, specified in BIP70. The request itself can expire, but the address cannot. That address can still receive Bitcoin and you will still be able to spend them. The expiration time does not matter unless you sent them the BIP70 payment request. In order to have sent someone that request, you would have had to save the request file and manually send it to them, so unless you did that, the expiration time does not matter.

Thank you for this answer! I created a second wallet in my electrum wallet to use with a different miner, never expired...and noticed that my personal miner file somehow change to 1 day expiration...and I could not change it back to NEVER...was freaking me out, LOL.
