Need help on local website construction

I like your idea and wanting to do it on your own.. That to me says a lot..
I would defiantly suggest using a outside source for local weather using the API and pulling only the information you want to display..
As for the calendar I've never even attempted to make one. I'm sure you could google something and study some source codes and figure out what you need to do to get it working.. I dont know if your looking to do something special with the calendar or just have a super basic one that shows the day on it.

Weather Api - https://openweathermap.org/api
Calendar in PHP - https://www.startutorial.com/articles/vi...dar-in-php
Calendar in html/java - https://code.daypilot.org/17910/html5-ev...pen-source

This should help get you started on it.. I am curious to see what you make.. If you get it working shoot me a DM with screenshots or something..
