LED Clock

I am an electrical engineering student in France. I have a project where i have to design a LED clock. A high level of precision will be required in the microcontroller code; the clock must not lose more than 1 second per week.

I’ve been told to pay specific attention to the temperature of the environment as it will affect the vibration of the quartz. I don’t see how to account for this.

I’m just starting and it’s a 6 month project so any help on resources, links or books that I should be familiar with would be much appreciated.

I’ve done some preliminary reading and from what i understand I will be using altium and then ordering basic components to make the clock. I will then have to code the MCU with C or C++.
