In April 2006, Google released a free online calendar application called Google Calendar. If you have a Google account, you can create a Google Calendar. If you don't have one, you can register for a free account.
You can use Google Calendar to schedule events and invite people to participate. By sharing folders, you can compare your schedule with other users. If everyone keeps his or her calendar up to date, it's easy to avoid conflicts. A single user can open multiple calendars and view all the scheduled events in a single window. Since this can get confusing, Google displays each calendar's events in a different color.
Google includes its search feature within the Google Calendar system. You can search for specific calendars. Calendar owners can choose to keep a calendar private or share it openly with everyone. It's also possible to create multiple calendars with one account. That can come in handy for organizations that have multiple customer bases. For example, a theatre might have one calendar for the general public that shows the times of performances and a second calendar for actors to let them know about auditions and rehearsal schedules.
Another Google product that's gaining popularity is a suite of applications that you'd usually find in office desktop software. It's the Google Docs suite of programs. Find out more about them in the next section.
