My H was dark and no contact with our 25th...on the 26th he was in town and we went out for a few beers and he asked, "So what are we celebrating?"...I told him, "Nuthin'"...and he sort of snickered...on of the few times I think he was actually thinking of us still married...
I wouldn't bring it up...just do what you want, celebrate your own hurdle and let it go...
