Do donation codes have an expiry date?

[Invoice]

I won a 9 day donation code because I am the winner of a DB tournament "Goat Format Weekly #92".

I am wondering, do codes have an expiry date? If so, when do they expire?

I ask because I want to save my donation code and use it during Christmas 2024. I wonder if it'll still work at that time?

no they don't expire but anyone can take it. when redeemed, it only lasts 9 days.
