Imagine that you use Outlook at work to maintain your work schedule, and iCal at home to keep track of your personal life, and you want to keep the two schedules together, but separate. You want to be able to share your Work schedule with work people, your home schedule with your wife, and nary the two shall meet.

The solution? Multiple calendars.

In your iCal, you’ll be able to see these events side-by-side, but if you want to share just one of those calendars over the internet, it will show only the events in that calendar to those who view it. (This also has the added benefit of showing you at a glance that you work too much!)

I personally maintain 5 calendars: Personal, Work, Class (I’m a full-time student), Church, and Birthday/Anniversaries. Makes it easy to keep my life nice and organized.

Here’s how you do it with iCal:

1. Open iCal. (duh!)
2. On the left-hand side, you’ll see a spot for calendars. Right-click in the blank space (Hold the Ctrl key and click, or click and hold) and select “New Calendar” (screenshot)
3. Give it a name.
4. Repeat as many times as you like

Now that you’ve done this, you can go read how to do the same thing with Google Calendar and Outlook 2007, and then you can read sync multiple iCal, Google, and Outlook Calendars to keep them all automagically synced together!
