My calendar events have disappeared

[JoCo30]

I used the Google calendar app on my Nexus 7 to set up a calendar. It took all day but I finally finished. Then I figured it would be good to sync all that work to the Google calendar on the Google web site so I told it to sync. Nothing went to the Google calendar, but all the events on my Nexus have vanished. Any idea where it went? Any chance I could recover it?

You might have saved the events on the Nexus 7 to the device's calendar. There is a difference between your device's calendar and your Google account's calendar.
