Past or Present Perfect?

[Tdol]

Why?

[EGrammar_Learner]

I haven't seen them for the last one month.

It is still going on that I have not seen them the whole last month until now. That's why I use present perfect here. Am I right? Thanks.

Say "I haven't seen them...." (present perfect). That is because it is ongoing. I haven't seen them for a month and I still haven't seen them (up to the present).

Like Harry, I would say for a month.

Regards,

If ıt was "for a month" yes yours is the correct one but it is "for the last one month"...

For the last month = in the period equal to a month coming up to now (not a calendar month, but an unfinished 30-day period), so it's prenet perfect.
