Question:
I know "My Calendars" works with iCal a Macintosh computer, but how do I make it work with my Windows computer?
Answer:

Before we get started subscribing to the calendars, you must have a specific piece of software
downloaded to your computer. On a Macintosh computer, you must have iCal and on a
Windows machine, you must download Sunbird. These directions will show you how to download the software and subscribe to the PowerSchool calendars:
