Level 2 ring in one day?

It was with a previous ring, but what happened was I upgraded my ring with less than hour in the day (so 11:15ish pm?), and the ring upgraded on the next day. If I were using a potion, then I'd have lost a day, because it counts when you trade in the potion as a day. However, because you didn't have to trade in a potion, you would still be able to get a potion to level it to 2. So technically, its two levels in one day, but you actually started the day before.

That's what happened for me. Iono...was there another way?
