Details:

the function datenum for some reason ignores the month

For example, performing a datenum for March 31st 2015 yields

datenum('2015-03-31 0:00','YYYY-MM-DD HH:MM')
ans =  735995

Now for doing it for the next day, April 1st, we get

datenum('2015-04-01 0:00','YYYY-MM-DD HH:MM')
ans =  735965

which is 30 days LOWER than the previous result. Next, use June 1st instead

datenum('2015-05-01 0:00','YYYY-MM-DD HH:MM')
ans =  735965

You get the VERY SAME RESULT, which means that the month is not factored into
datenum at all.
