Create events reoccurring every (x) days BEYOND 14

Create events reoccurring every (x) days BEYOND 14 - Users - How do I? | Google Groups:

"Ok, finally got it. To clarify for anyone else, you must TYPE EXACTLY
WHAT YOU WANT on the quick add entry line.
So you have to click quick add and then type 'Server payment on the
26th all day every 30 days'. I was trying to use the built in forms
that for some silly reason won't let you go over 14 days. I knew I was
missing something, I didn't realize an even could be created this way.
It still doesn't make any sense to me why you can't do it the normal
way but I digress.

Thanks for the help Gerry."
