Another piece of news involving the Google Play Store revolves around the Google calendar app which is now available for you to install on your Android phone if you don't already have it. Many Android models, as you can guess, have had the stock Google calendar replaced by the OEM. The Google Calendar app is the one that you would find on a Nexus model.
Some of the additional features include the ability to snooze events from a notification if you're not ready to get up yet and want the alarm to go off later. You can have "I'll be late" messages automatically sent to your event participants under certain circumstances and pinch-to-zoom can be used to move in and out of a day. Lastly, the Google calendar app allows you to set a home time zone to help you better handle your planned events more efficiently while traveling.
There are some caveats. HTC devices don't seem to want to work with the app and you need to be running Android 4.0.3 or higher.
