Expected circulation it's not exact and can vary. That's what you're going to see it on that table according to the Wikipedia block schedule:

So... according to devs schedule published on the OP, 26 January 2015 (estimated) can be the date that you're looking for

This is helpful, thanks, it is good to be reminded of the block reward reduction schedule. So basically this price action is driven by the upcoming block reward reduction. Makes sense. Doge has hung in there and with merged mining looks to be a survivor. So there will be some demand as there is still a decent community supporting it. However, I wonder if the price relative to BTC will hold since there will still be a lot of coins out there? I don't see a demand side boost.
Good Luck everyone!
