Trying to remember how to say things like:

I will be there for a week.

I was there for a year.

Etc.

Is it "i rith" I'm looking for?

I swear, every time I learn something new, I forget something I once knew!

'ar feadh' is what I'd say.

'i rith na seachtaine' is during the week.

With the future tense, you'd use "go cionn".
With the past, you'd use "ar feadh" (or other things)

Beidh mé ansin go cionn bliana

Bhí mé ansin ar feadh seachtaine.

Are there alternatives to 'go cionn' for the future tense as that does not sound familiar to me?

I don't think that's quite right.

I think go ceann/cionn only works if you are counting from now.

Ar feadh refers to any duration past or present or future that doesn't have a starting or end point now. (confirmed in De Bhaldraithe under "for".)

To say "for" a period up to the present, you use le ~ (anuas).

These would have been my thoughts.

le dhá sheachtain anuas for the past two weeks

Ní bheidh mo chara anseo go ceann seachtaine My friend won't be here for another week

I'd say, 'i gceann' for this.

_________________

i gceann seachtaine is slightly different. Ní bheidh mo chara anseo i gceann seachtaine means My friend won't be here in a week if I'm not mistake. Somewhat of a subtle difference.

I misread what was going on. I was thinking of a context such as, 'Beidh mé ann i gceann seachtaine' meaning I will be there in a week's time as in denoting starting time and not duration of visit.
