static page in sidebar

hi friends, my question is simple – I hope the possible answer too: I just installed a new wp for an event coming up in spring near my home town dresden. https://www.landeserntedank.sfiv.net.

Therefore I need a static page in wp, that shows all steady items like date, time, location an so on.

I made a new page. ok. now I want to appear this static page on the surface in the sidebar.

Does it work
1. either automatically by klicking a special installation button in the backend
2. or by linking it to the linklist to the front end?

Thanks for all hints and comments
