Here you go Tom. I think this is what you are looking for. There's probably a more streamlined way to implement it, but this seems to work nicely. Sorry for the VB-style variable names (grin) Hope you find it useful. -Eric. Here's the (ONLY) DTML used to test the functions: -----8<-----8<-----8<----- <dtml-call expr="REQUEST.set('d', ZopeTime('1999/11/21'))"> Here's the result of dateInNMonths on November 21, 1999 + 6 months:<br> <dtml-var expr="dateInNMonths(this(),d, 6)"> <br> -----8<-----8<-----8<----- I implemented it using two "Python Methods" as follows: -----8<-----8<-----8<----- ID: daysPerMonth Parameters: ZopeDateTime <-- Pass in a Zope Date Time object Function: if ZopeDateTime.isLeapYear(): intDaysInFebruary = 29 else: intDaysInFebruary = 28 strMonthName=ZopeDateTime.Month() dicDaysPerMonth = {'January':31,'February':intDaysInFebruary,'March':31,'April':30,'May':31,'J une':30,'July':31,'August':31,'September':30,'October':31,'November':30,'Dec ember':31} return dicDaysPerMonth.get(strMonthName, 0) -----8<-----8<-----8<----- ID: dateInNMonths Parameters: self, ZopeDateTime, Months Function: days = self.daysPerMonth(ZopeDateTime) - ZopeDateTime.day() + 1 i = 2 while i < Months: nextDate = ZopeDateTime + days days = days + self.daysPerMonth(nextDate) i = i + 1 days = days + ZopeDateTime.day() - 1 return ZopeDateTime + days -----8<-----8<-----8<----- -----Original Message----- From: Eric Walstad [mailto:Eric@Walstads.net] Sent: Tuesday, November 21, 2000 10:19 AM To: Tom Deprez Subject: RE: [Zope] Date Hi Again Tom, OK, This is an interesting one that I may need later on.

In certain circumstances the method below will give me a wrong month. Tom. At 09:29 21/11/2000 -0800, Eric Walstad wrote:
Hi Tom, I have a Python Method (or whatever they're called now) that uses the following line d = self.ZopeTime() + days So, you could do something like: d = self.ZopeTime() + (days * 30 * 6) However, not all months are 30 days so this isn't totally accurate. But, maybe it's good enough for your needs.
Hope it helps, Eric

Does someone knows how to calculate the date after 6 months of a certain date?
eg ZopeTime() + 6 months?
Is there an easy formula for this? Or do I've to check myself for a new year, leap year
Tom.
