Here is how to subscribe to it on iPhone.
On an iPhone from settings, accounts & passwords, add account, other, add subscribed calendar, and paste the link below. Let me know if it works or not. I made this calendar a couple of years ago basically just for my wife and I to share. It takes a good bit of work, so I thought others might as well get to use it too.
