Need help on local website construction

because i'm stuck inside my house for now, i'm going to attempt to make a local website that'll have a homepage that has like local weather, time, and maybe interactive calendar. witch would all be hosted off a dedicated "server"(old dual core pc) running Ubuntu server 18.04. i was wondering the best way to go about this should i hard code it with like weather API from a outside source or something if anyone has any references to give me for me to research up on please let me know.

FYI i know there's probably tons of websites out there or would be more convenient to look up "my local weather" and like use google calendar or something but i want to attempt to make it and have it over LAN, why? idk because i want to lol
