The screen you reference is an input only device, that is, it accepts output from other sources and presents the information. It is not, per se, a stand-alone computer for processing information in the manner you describe.

One option you can consider is a device known as Sparkfun Microview.

This device is an integrated Arduino with OLED display. That's only half the objective. You'll also have to have a programming interface (referenced on the site) as well as an external input for RTC (real time clock). Rather than provide a link, an Amazon search for "Arduino RTC" returns many options. Kit form (assembly required (minor soldering), fully assembled, with and without battery.
All of the above requires, at a minimum, a power source for the Microview and a breadboard on which to make the connections. One can, of course, design a PCB to consolidate the components.
The programming portion is easily accomplished (relative reference) by researching that aspect via the internet. There are tutorials for the Microview, which by necessity include Arduino programming, as well as supplemental tutorials for the RTC. Sparkfun is known (by me) for providing good online support via these tutorials.
If you decide to travel this route to your goal, you may have Arduino specific questions which would be acceptable to this SE.
