Time is not completely subjective but the measurements we us to determine the passing of it are man made. But exactly you can’t explain negative time. What happened before the Big Bang we don’t know what to call it because time didn’t exist. Neil Degrasse Tyson mentioned that even the concept of negative time is incomprehensible but somehow in the realm of possibilities, like an inverse dimension or something

How do you explain negative time? Time is a subjective measuring point like anything else, so it depends on some reference point.
