You can share your calendars with other people to show them what you are doing, or simply to let them know when you are free or busy. There are two basic ways to share your calendars or calendar information. You can:

•	Publish a copy of your calendar on the Internet so anyone can view it using a web browser or subscribe to it using iCal

•	Export the events on a calendar and send the file to someone to import on their computer

Publishing a calendar places a copy of the calendar on a web server, at a specific URL. Published calendars are "read-only," and cannot be changed by anyone who subscribes to them. You can publish your calendar on your .Mac iDisk, or on a private WebDAV-enabled server. (A WebDAV-enabled server is necessary to publish and share calendar data.)

If you publish on .Mac, anyone you send the URL to can view your calendar using a standard web browser. They can also use iCal to subscribe to your published calendar. To publish your calendar on .Mac, you need a .Mac membership. To sign up, click the .Mac button in Internet preferences.

If you don't have a .Mac account, you can publish your calendar on a private WebDAV server (for example, on a server where you have your own personal webpage). Other users can use iCal to subscribe to the calendar you published, but they won't be able to view your published calendar using a web browser.

You can also export your calendar information. If you export your events and then import them on another computer, the imported events can be edited. However, if the events are changed on the second computer, it will no longer match the originally exported calendar.
