I've been using Google Calendar, but it's stopped working for the second time in twelve months.  It's stopped sending me my daily agenda, or any reminders at all.  Last time, I managed to fix it by unsetting and resttting my notifications, but that hasn't worked this time.

Looking on the web, I discover that lots of other people have had this problem.

Can anyone recommend a good calendar programme?

I have a large year at a glance calendar on the wall above my computer, and that serves for most things - but I do find the automatic email reminders are useful for things where I need to catch a bus on time.
