Is “Now”, for me, mathematically the same as “Now” for people on the other side of the world?

I have only a very vague awareness of the idea of relativity but I’m aware that there’s a concept that people in orbit experience less time than those on the planet due to gravity, in some way.

Does this mean that the idea of “now”, as in a moment that is right now, is marginally different for people in other places? Are they experiencing a moment that is in my objective future/past, in a mathematical sense?

It’s not even possible to define ‘now’ mathematically for one person. What you see, what your brain is making sense of and what your body is subject to all happen at different times.
