We observe that space- and time-crystallization effects in multicomponent superfluids -- while having the same physical origin and mathematical description as in the single-component case are conceptually much more straightforward. Specifically, the values of the temporal and spatial periods are absolute rather than relative, and the broken translation symmetry in space and/or time can be revealed with experiments involving only one equilibrium sample. We discuss two realistic setups -- one with cold atoms and another one with bilayer superconductors -- for observation of space and time crystallization in two-component counterflow superfluids.
