Download the latest Google Calendar for Android

Google Calendar for Android gets crossdevice notification sync
The simplest updates are sometimes the best. See the latest update to Google Calendar for Android as an example: the release adds notification syncing between Android devices, saving the trouble of clearing multiple alerts while hopping from tablet to phone and back. That's the only major addition, but it could represent a big time saver for anyone with a busy schedule. If you're in that camp, you can grab the new Calendar now through Google Play
