Google Calendar app is now available for all Android devices as long as they run Ice Cream Sandwich 4.0.3+ or Jellybean. Previously the application was shipping with select smartphones like Nexus S and Galaxy Nexus, and now everyone can join the party.
Aside from the standard calendar features like creating, editing, deleting events and responding to invitations, there are also few extras that help you manage your time and communication more easily. For instance, you can snooze events directly from a notification if you’re not quite ready and want to be reminded later, and use predefined messages to send quick “I’ll be late” updates to your event participants directly from the notifications or the event itself. In addition, there’s pinch to zoom in and out of a day, as well as the ability to set a home time zone to help you manage your time better when traveling. Finally, the sync period has been expanded so you can review past events from up to one year ago directly on your device.
