How do I export my Bold 9780 calendar?

I had a baby Oct of 2013 and made calendar entries for each day of his life until age one. Now I would like to export those but I don't know how. I've tried doing a sync with Google Calendar but it isn't working. It seems the only answer is to download the Blackberry Desktop Manager to my computer but I wonder if I'm missing another option here. Thanks!

This is the calendar on your BlackBerry? You are going to have to back it up and sync with Desktop Manager. Now if you made the calendar in Google, you would have a sure fire way to save and sync....
