Fixed problem whith calculation of the number of days in a month which was causing errors on fetching the digest for the month of February.  Experimentally, it appears that c.getActualMaximum(Calendar.DAY_OF_MONTH) returns 31 for February if the day of month is left uninitialized.  Arbitrarily setting day of month to 1 fixes the problem.
