Notification Center should have the date too

I have an iPod touch last generation and i have the calendar app in the bottom deck so every time I have to check the date I just press the home button (if I am writing a email or something like that) but I think it could be a lot better if the notification center had the date too! Either in a place designated by apple or by the user. In fact I don't even use the weather app. I will really use the date instead of the weather. Right now I disable the weather.

Also I don't get all the Facebook notifications (I get some) do I have to leave the app running to get all the notifications or can I close the app (closing app by tapping home button holding and taping red dot)?

Does anyone else feels the same about the calendar app?

(yes I am running ios5)
