We find the claim that time is not real in both Western and Eastern philosophical traditions and, more recently, in contemporary physics. Yet it seems unlikely that when McTaggart, Godel, Barbour, and Dzogchen practitioners say that there is no time, they are denying the existence of the same thing. This essay is an attempt to set out a taxonomy of different views about what it takes for there to be time and, alongside that, a taxonomy of views about whether or not there is time.
