[Grammar] Which Tense to use?

[Kotfor]

Which tense is not acceptable after "starting from today" in the following list?

1) Starting from today I am working here.
2) Starting from today I work here.
3) Starting from today I will work here.
4) Starting from today I will be working here.
5) Starting from today I am going to work here.

Wh​ich do you think is/are incorrect, if any, and why?

 

[Kotfor]

I find all of them acceptable in a certain context. But I am not sure if I am right.

 

[Raymott]

None are wrong, but I'd put a comma in the middle of all of them where one would normally pause during speech.

 

[Barb_D]

And I'd delete "from" in all of them. Is that an American difference or just my personal preference, do you think?

 

[emsr2d2]

I'd accept either "Starting today" or "Starting from today". I admit that it's probably unnecessary and yet it sounds perfectly natural. I would also add the comma. I agree that all 5 are perfectly acceptable sentences.

Kotfor - was this an exercise which suggested that at least one of those was wrong?
