Usage notes
In Japanese, (the number 4) can be read as either "shi" or "yo/yon", depending on the context. It is a bit unusual to use both readings in a single sentence and, unless you are simply counting, they are not interchangeable. Compare (yoji, not shiji; "four o'clock"), but  ["fourth month", i.e. April] is always read shigatsu, never yogatsu.
