I want to read the information that is updated on the web page at a specific time and put it in Excel.

I think you should make web crawler by analyzing html for a specific web page http://www.investing.com/economic-calendar/.

You can create a program that corresponds to the above two. The address below is the process of creating a web crawler through a language called Python. I think it would be good to refer to. Basically, it won't be easy because you need to understand the programming language.

As far as I know, web crawling itself is not illegal, but it is illegal to use crawled content without permission. I don't think it'll be a problem for personal convenience.

If you use Excel, you can read the data using Visual Basic.

For web crawling, If you use node.js, it can be easily implemented using the chemistrypm module.
