>Is there a function to get the number of days in a month. >eg. the number of days in any month of any year. > >Thanks >Andrew Func DaysInMonth Lpara date_ld Local days_ln, first_ld * get the first day of the month first_ld=date_ld-day(date_ld) * difference to the first day of the next month days_ln=GoMonth(first_ld,1)-first_ld retu days_ln The function I've sent few days ago is not sure to work on 31st - may since GoMonth of 31st of may is 30th of June and so on. This way we calculate the distance from the first day of the month to the first day of the next month - every month has a first day, doesn't it?
