After an extended public beta period that began in July, Apple on Thursday announced that MobileMe Calendar is now available to all MobileMe users.

[ad#Google Adsense 300×250 in story]Apple significantly updated MobileMe Calendar’s interface to more closely resemble the calendar app included in the iPad. The new calendar service has redesigned day, week and month views and a new list view.

But there’s a lot of new functionality under the hood, as well. You can now share calendars with others you’ve invited in either read-only or read/write modes. You can create a read-only public calendar as well – useful for sharing calendars with groups. Guests can also be invited to events even if they aren’t MobileMe members, creating RSVPs for group activities.
