English is ever-changing - dropping of preposition

[Tedwonny]

The tenancy period ends 30[SUP]th[/SUP] June. It may be possible for them to stay for a couple of extra weeks into July

I come across this sentence the other day and it reminds me of the increasingly common phenomena of dropping certain prepositions before the dates. Is the above sentence correct [including 'into']?

Can we now say: We'll start 5th June instead of We'll start from/on the 5th June?

Thanks

Informally - yes.

(Note that it's 'the. . .phenomenon'; phenomena is plural.)

Incidentally, you would not say "We'll start 5th June instead" in AmE, even informally. You would say:

We'll start June 5th instead. (informal)
or
We'll start on June 5th instead. (semiformal?)
or
We'll start the 5th of June instead. (more formal?)
or
We'll start on the 5th of June instead. (most formal?)
