How do I change UTC to CET?

I'm curious to know, how exactly do I convert the time from UTC to CET? Is there a specific formula or method that I should follow? I often find myself needing to adjust for time zones when working with international clients or in finance, so I'd appreciate any guidance you can provide on this matter. I'm hoping for a straightforward and easy-to-understand explanation that will help me make the conversion quickly and accurately.
