Local muni course is redoing all the greens how long and I screwed for?

My local muni course that I play is redoing all 18 of their greens since they’ve gotten pretty rough.

For anyone that has played a course that did a full green rebuild, how long were they out of play? And how long before they were back to being good?

I’ve heard timelines all over the place so I’m curious what other people have actually experienced.
