in reply to ALTERNATIVE TO CRON.SH
If you leave your computer at home on all the time you can use your local machine's cron (or 'at' for Windows) to trigger a remote event on the server (via CGI) that sends you your email reminder as necessary. Of course, if you're going to do that you might consider doing everything on your local machine and cutting out the server entirely, but that might not be feasible if (for example) your server handles all your remote access to the calendar.
