How to use calendar without Google

I unchecked the calendar but now there is nothing to use I do not want it to sync with Google but just use it on EM 

Go to Menu > Tools > Accounts and click on the General tab for your Gmail account. Untick Google Calendar. (this is what you have done)

Go to Menu > Tools > Settings > General and tick Show Local Folders.

You will now have a local calendar that is not synced.

Thank you very much
