Guide Review - Google Calendar - Free Online Calendar
Of course, you'll spend more time looking at your calendar and entering events than searching. In Google Calendar, you can pick a time with the mouse to add an appointment or use the slick "Quick Add" field that understands some "natural" language (such as "dinner with Kavindra tomorrow at 7pm"). Repetition options, thankfully, are flexible. If you use Gmail, you can turn emails into events easily, too. Sadly, that does not work with other email programs — by forwarding emails, for example.
In reverse, Google Calendar sends you as many reminders as you like not only to any email address but also via SMS or popups in browser and OS task bar. You need not stick to your browser for browsing your schedule either: Google Calendar can be accessed via mobile devices (including iPhones, BlackBerries and Windows Mobile), Outlook and CalDAV (Mozilla Sunbird, iCal).
Your calendar, alas, is not yours exclusively: everybody wants a share, or at least know what you're up to. In Google Calendar, you can make entire calendars public for the world to see or share them with but a few. The setup is flexible but does not extend, in even more granular a fashion, to individual events.
What you can do, of course, is invite anybody with an email address. Even if they do not use Google Calendar, you can track their responses, and they can invite more participants, comment, and add the event to their calendar no matter their software. Unfortunately, the "Accept" and "Decline" buttons programs such as Outlook use only work with your default calendar.
Google Calendar also lacks a way to suggest multiple times for the participants to choose and makes no effort to find free time when you seek to fit something into a busy schedule. The task manager included is the one you know from Gmail: functional, but limited.
