As from VERSUS as of

[Tung Quoc]

Hi,

1/Yesterday I wrote as from now and Mr.Miscaber corrected from now on. Why did you correct that?

Are they the same meaning and interchangeable? If not, what is the difference btw them?

2/ Do as from and as of have the same meaning and interchangeable?If not, what is the difference in meaning btw them?

"as from now" cannot be used to mean "from now on" but ''as of now" does mean "from now on".

"as from now" can mean "because from now". I won't be able to help you any more (because) (as) from now I will be too busy.
