google does claim they will pay you by the 25th of this month
Where does it say this? On the payment page they ask you to contact them if you haven't received a cheque for two months prior. That is, by the 25th Feb you should have received the cheque for December.
What they do say is that they'll send the money before the end of the month after. Ie they send January's money before the end of Feb.
But when you get it is a different matter. It seems EFT takes less than 24 hours in the US, up to 4 days to the UK. Cheque will obviously be subject to post etc..
