When does 12 Deals on PSN sale end?

I'm probably getting a $20 PSN card for Xmas from someone and I want to use that money on Xmas day towards some games on sale in the 12 deals of PSN sale, namely Guacamelee and others.

But I can't find an end date for this sale. Will it end on Xmas eve? Xmas day? or later. I've looked but the Playstation Blog updates don't put up end dates, just start dates for sales and these game's description's don't always list when the sale will end.

Thanks.

deals lasts 2 days.
