Chill it, slice it, wrap in meal size portions.
Wrap tightly in your favourite clingwrap, then freeze.
Keep a week's worth unfrozen.

Good to infinity and beyond - well, at least well past Xmas anyway. If it lasts that long and you don't overdose on it.

The curing process preserves it.

Go easy on feeding it to pets, salt and all that.

I have a sensitive tummy and I am not going to eat any meat left in the refrigerator unfrozen
for over a month!

Don't forget to make a delicious ham and bean soup.
You can look up a recipe, you use the ham bone and some of the ham.
In the grocery store you might find the beans and the flavoring all packed in one box.

you can even do the prep for a particular dish before you freeze, such as your ham/scalloped potatoes.
Cube or chop the ham as you would for the dish then freeze it. It will be ready to go when you make the recipe.
SLice some for sandwiches. Bag up some for red beans and rice (A good ham bone makes the ultimate red beans and rice. )

Enjoy your ham!

I haven't had any for years, wifey is a militant vegan and doesn't eat anything that had a face before it died.
She has eyes like an eagle, and I'm being watched. Makes me an involuntary vegan. *Sad Face emoji*

Involuntary vegan? I would not be remotely good with that. While I want to respect individual choices, shouldn't you be making your own choices? Why should she be dictating you?

Keep in mind that humans evolved as omnivores. Also cooking food was hugely important. We are not evolved to eat only uncooked food. So anyone who tries to claim we shouldn't eat cooked food, or we should not eat meat hasn't a clue about human evolution. Personal choices are one thing. Dictating to others, not so much.

So eat what works for you, including meat. She can do what she wants, that's fine. But you should also do what you want, and she should NOT be dictating your behavior or food choices.

I already know ham freezes well, but what I'm trying to figure out is how long I have before I absolutely must freeze the ham. Do I actually have well into December? Trust me, I wouldn't wait until the last minute, which might be December 31, as that's the date given on the ham as the eat or freeze by date. but am I okay into the beginning of December? Or should I apportion it and freeze earlier than then?

it doesn't matter what the label says - that applies to unopened food. It is now leftover and you should freeze what you don't use in the next couple days. As this points out, pathogens that can cause food poisoning can grow at refrigerator temperatures.

That's a lot of ham! I try to buy the smallest I can find with a bone (because it goes great in bean dishes), and use it up within a few weeks.

Hams were designed to be kept for a long time, at least traditional brined or smoked ones were. (when I once visited my rural in-laws I got to meet this year's pig, eating watermelon rinds in its pen, and last year's pig, hanging in the smokehouse). I'd keep it in the fridge - but not wrapped in plastic: I've accumulated a lot of reusable take-out containers during lockdown, and I find those are better for storing food. 4-6 weeks seems reasonable to me if you keep it covered and refrigerated. I've never frozen the meat - although I have ham rinds and bones in the freezer.
