Hello,

I'm not sure what you want to do with the 'extra' days each month. But
if what you want is to bin the dates into 5-day consecutive groups then
I suggest you...

(1) Convert your dates from strings to Julian day values. You need to
used some string processing before you get to using JULDAY().

(2) Sort your dates into 5 day bins using HISTOGRAM().

H = HISTOGRAM(myJulianDayValues, START = JULDAY(8,1,2001), BIN = 5, $
REVERSE = r, LOCATION = binStartDates)

(3) Use the REVERSE_INDICES to extract the records for each 5 day group.

Hope that helps.

Cheers,
Ben
