Can 'from now on' be understood as 'from this day forth'?

[Anna.ha]

If they are different, would appreciate if someone explain them to me.

Thanks

Hi Anna,

'From this day forth' is more of a literary expression and would be used in formal statements but it has the same meaning as 'From now on'.
