Imagine that you use Outlook at work to maintain your work schedule, and Google calendar 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 master Google Calendar, you’ll be able to see these events side-by-side, but if you want to share one of those calendars with select people, it will show only the events in that calendar to those people. (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 Google Calendar:

1. Log in to Google calendar. (duh!)
2. Click on the Settings link in the upper-right-hand-corner, next to your email address (screenshot)
3. Select the “Calendars” tab, and click the “Create new calendar” button (screenshot)
4. Give it a name (required), Description (optional), and Location (Optional). Make sure you select the right time zone, and hit the big “Create Calendar” button
5. Repeat as many times as you like

Now that you’ve done this, you can go read how to do the same thing with iCal and Outlook 2007, and then you can sync multiple iCal, Google, and Outlook Calendars.
