January 1st was a holiday as well as a Saturday. Sunday January 2nd was another day off, a day of rest, a day for coming back from vacation, etc. Those days are so variable you might as well write them off.
The only real days of consequence for adsense earnings were two days, Monday and Tuesday. Today, the fifth of January, hasn't ended yet.
I think judging two days of earnings year over year is a bit too small a sample and arbitrary to be useful for drawing conclusions about a trend. Two days following a major holiday is too small to be used to draw conclusions of any kind. Certainly it cannot be used to determine what the rest of the month will be like, much less the rest of the quarter and still less the rest of the year.
