Is this similar to the story that it rains more on the weekend ? Didn't the analysis show that if you segmented the data into arbitrary chunks it always came back with higher rainfall at the start of end of the period - so if you broken the data up into blocks that went from Wednesday -> Tuesday it would come back and say it rains most on Wednesday. Wonder if something like that is going on here - I am down with the argument about stress and going back to work making it worse on a Monday :)
