I have six years' experience? Six years experience?

[WeasleyWoman]

I should know this but I don't and have looked at it too much now!

I have six years' experience in cockwombling.
The apostrophe is wrong...isn't it?

I'm a bit zoned out from Brexit stuff so will try my hand at this one

Isn't there an 'of' missing, as in

"I have six years of experience"

in which case it isn't possessive, the years is just the duration of time? So no apostrophe needed.

No it's fine but doesn't seem to be taught or used. The time of 6 years so apostrophe.

5 years' time

Watching!

Woodhill is right. If you want confirmation, think of one year's experience and it's obvious where the apostrophe goes.

Yes, you need the apostrophe. I can't remember why but you do! (I write lots of contracts and it's always a week's notice, three month's notice etc.)

Three month's is wrong

Aaaggghhhh! Three months'. Bloody autocorrect!

Yes one month's notice or three months' notice.

I know. I didn't type that, promise!!!

The experience of six years. So the apostrophe is in the right place.

Does the experience belong to the years or to you?

Years'. It's short for years of experience.

You definitely need the apostrophe. It's one month's experience, and three months' experience.

Thank you

It's a possessive apostrophe - the experience belongs to the years. The apostrophe does need to be there.

It isn't taught though in school in my experience but I was taught it so always use it.

I was taught you use an apostrophe in a timeframe
