texte = How do I get the last day of last month? I could do the math on the number of days since 00/00/0000 or I could do the math on the {dates} but in both cases I would have to do a lot of conditionals: [if ("[thisMonth]"="[april]") | ("[thisMonth]"="[jun]") | ("[thisMonth]"="[aug]") | ,etc....] [then] [text]ThisMonthsLastDigit=30[/text] [/then] [else] [text]ThisMonthsLastDigit=31[/text] [/else] [/if] [showif [URL][thisMonth][/URL]=feb] [text]ThisMonthsLastDigit=28[/text] [/showif] [if ("[thisYearTYPE]"="[leapyear]") & ("[thisMonth]"="[feb]")] [then] [text]ThisMonthsLastDigit=29[/text] [/then] [/if] and there are deeper cycles, I understand, like every 10th year we skip a leap year, (or something like that), etc. SO I figure it is a waste of time to rewrite the date libraries WebDNA uses. So back to my question: Given that I don't know what month it is now, what WebDNA logic/code do I need to use to figure out whether last month's last day's digit is "28", "29", "30", or "31"? ...and if this is any easier, what I am ultimately after is the exact number (a date "expressed as days since 00/00/0000") of the *first* day of last month, and the *last* day of last month.
