[Grammar] Preposition: Monday or on Monday ?

[toutoublue]

Dear all,

I'm stuck on the question about the use of preposition. I've found these two phrases in the same article from CNN:

CEO Marissa Mayer confirmed Couric's hiring in a Tumblr post on Monday.

S&P Capital IQ analyst Scott Kessler said in a note to clients Monday that he thinks it makes sense for Yahoo to do so.

PS: Tumblr is the name of a company.
Why is there no preposition preceding "Monday" in the second phrase ?

Thanks to whoever would help me out.

Some people often drop it, especially in less formal situations.

It's commonly dropped in speech - less so in writing but it's still possible.

Q - When are you writing the report?
A - I'm writing it Tuesday.

Q - When did you last go to your favourite restaurant.
A - I was there Friday evening. I'm going again Wednesday lunchtime.

I wouldn't recommend using the construction in an exam/test situation.

I'm still a little bit confused.

Let's take the example given:

I was there Friday evening.

If I don't want to omit the preposition, I'd say "I was there on Friday evening". Furthermore, if it is not Friday evening but this evening, as the logic goes, I could say "I was there on this evening" if I wouldn't want to leave out the preposition. But in fact, I've always heard "I was there this evening". I'm wondering whether "on this evening" is grammatically correct or not.

In the same article, I saw these phrases "He retired early this year." "in a report released this morning". Why not "He retired early in this year" and "in a report released on this morning" ? Are "in this year" and "on this morning" correct?

Thanks a lot.

That's fine.

That's not.

No

Not when you are referring to the current year/morning/etc.

Note to the learner: in a living language, don't expect the prepositions to be purely logical. What is correct is often just what people have been saying for a long time. No reason is necessarily going to be available.

Thank you so much! Now I got the reason why we don't use 'on' or 'in' before 'this year', 'last year' and 'next year'. Because the reference is the current year.

But how about 'of' ?

I made the following two setences in a context where the TV program was broadcast last Friday:
Let's talk about the TV program last Friday.
Let's talk about the TV program of last Friday.

Are they correct and natural?

Thanks a lot!

The second one is OK but, depending on the exact context, "Let's talk about last Friday's (TV) program" might well be better. The first one is not OK.
