Using calendar without syncing?

[MIKEgogogo]

I have a customer that wants to know is it possible to use the calendar on the phone without having to sync it up with any other source. She doesn't have gmail and does not use outlook, she just simply wants to be able to use the calendar and mark events and notes on days for reminders but when she opens up calendar it tell her that the calendar is not synced up and will not work properly, or something like that.

If she has a android, I thought u need a gmail account. But there is a setting in google sync settings, just uncheck the settings she wants...
