In all your games? Today is the 12th of Sun's Height, 4E202 for my main character. I never got out of 434 in Oblivion, I don't think. And I think I only ever got to 429 in Morrowind. It's a small thing, but I think it's neat to see the passage of time.

current game only the 18th of frostfall

I have 18th of Evening Star on mine.

I have many different characters, so I'm stuck in the 4E201 right now
