Time tracking app made with tailwindcss and javascript

This is not complete as I would like to make changes to the tablet view, I had wanted to make the same design for desktop, but scale it down for tablet screens, but I think making it like the mobile design but wider is the best option here.

I would like some advice on how to use the JSON data to update the site based on the relevant timeframe that is clicked. I am still not very good with JS, and I have never worked with JSON either, this is my first time, so any advice would be greatly appreciated.

Thank you.
