I took 10-14 days to go from NWB to FWB in the boot, once allowed to do so - six weeks post-op and a further 7-10 days not in the boot to go PWB to FWB.
It's safest not to rush things - if you try to bear too much weight too soon and re-injure the leg you'll take a lot longer than if you take an extra week or two to get crutch-free.
Can you get cheap ice grippers that will fit over the boot? Or a very large woolly sock over the whole thing might help.
You definitely don't want to be rushing into walking if it's icy and there's a real risk of your slipping and rebreaking...
