Astronomy/time being relative

Question
how and why is time relative? relative to what?

Answer
Hi,
relative to the observer!
If you are moving very fast, time will slow for you, but you will not notice at all! Observers external to your frame of reference will notice the change.

So "relative to what", has the answer "relative to the observer, or alternatively to the "frame of reference".

But all this holds true only when one of the observers travels very very close to the speed of light (or sizably so).
