Is the meaning different? I'm struggling to see how "from September 20th" would have a different implication to "starting from September 20th" (or similar) given the context.
The meaning is the same, it just sounds weird to my ears in the same way that “since years” does
(Also I just noticed the extra “it” in my previous comment, oops).
