I have a business I just sold which has all my 'billing invoices' (about 3000 of them) as notes attached to calender entries. In my current business, I need to search my calender frequently. As you can imagine, having 2000 invoices in my calender (among a lot of other entries) makes it time consuming to search.

I'm looking for an App that allows me to purge events longer than 1 year ago (for example 'purge all events greater than a year ago') The default purging in the palm calender is 1 week, 2weeks, 3 weeks, etc. There is nothing longer than that.

Any ideas?
