Re: Date addition problem

That should not effect it, if i am adding $i * 7 days each time then i should get the date that comes 7 days later irrespective of how many days are in the month, shouldn't I ? 8 * 7 = 56, 56 days after the 07-09-05 is 02-11-2005. Thomas Munz wrote:

Cause 9th month have 30 days but 10th month have 31 days. You don't check the amount of day there... :) on Wednesday 29 March 2006 14:51, Adrian Bruce wrote:

Hi I am having an unusual problem when trying to calculate dates in advance from a start date. the code below shows a loop where by on each run an increasing number of weeks is added to the start date, this works as expected up untill the 8th time where for some reason it produces 01-11-05 instead of 02-11-05. I am at a loss as to why this would happen when it works perfectly for all the other dates. where am i going wrong?
