Is there a way to customize a reminder or an event on iCal to alert me on the last weekday (business day) of every month, without buying an app?
Make an event and in its edit window select Repeat > Custom > Monthly > On the last Weekday. Then save the event.
(much easier than what I just posted)
There is no 'custom' option
It is an option under 'none', 'every day', 'every week', 'every month', and 'every year' in the repeat menu in iCal's edit window.
What version of iCal are you using?
The iOS Calendar interface is much more simpified than that of the Mac application and you cannot do it on there. I have heard that you can do more using Siri, but I don't have a device to test that on.
