Can someone recommend a calendar program?

[Tyrannocaster]

I need a calendar/alarm program that will display an alert and I'm having trouble finding one that will allow me to set events up that repeat every two weeks (rather than on a specific date). I also need to have a couple of events on the 1st and 3rd of each month, but it seems like all of the calendars will do that, so the hangup is the biweekly reminder.

I don't want to mess with cron - I used to do that back in the days of the Amiga but I have no desire to go back to that, LOL.
