How to make the site think that today is a different date?

Question

Web development

It is necessary that when visiting the site, the site thinks that today is a different date

Answer 1

No way. A normally written site determines the date by the clock on its server.

Answer 2

man date
But this implies that you have access to the site

Answer 3

Change the date on the computer (this will only work if the site receives the date from the client, otherwise they don’t)
