Calendar on Dashboard?

I used to a long time ago have a plugin or something that had a calendar on the WordPress dashboard and I am looking for something like that again. I am NOT looking to have a calendar for my readers but instead one for myself when I log into my self-hosted WordPress site to my dashboard that allows me to “schedule” posts by just putting in a topic or something into a calendar that I can then do a blog post on.

Is there any plugins for this? I have searched the plugin directory as well as google and can not find anything. All I see are plug-ins that allow you to put a calendar on your website, but I want this one just for me on the dashboard.

Thanks
