I said "reconition" rather than "celebrate" because a lot of the things I have in mind wouldn't be "celebrated" per se, although honoring the good parts of them would sometimes be part of the recognition.
One thing that bothers me about a lot of standard recognition rituals is that they don't make room for the "wrong" emotions. At a wedding, you have to be happy. At a funeral, you have to be sad. You're not allowed to talk about being sad at a marriage or happy at the death of a loved one, even though you might well be feeling such things.
- Death of a pet
- Deaths of people who aren't immediate family -- you might attend the funeral but that's pretty much all the mourning you're allowed publicly.
- A divorce coming through.
- Breaking up with a partner. (Often there is a lot of spontaneous support around this but not necessarily formal recognition per se.)
- Anniversaries of deaths-of-loved-ones, divorces, or break-ups. (We publicly celebrate the anniversaries of births and ongoing relationships, but not the anniversaries of endings, even though we darn well *feel* the anniversaries of endings.)
- Anniversaries of relationships that don't look "spousal." How about celebrating the anniversary of being single? Celebrating theanniversaries of friendships?
- Moving out of an old home.
- Having a parent or child or roommate move in or out of your home.
- Our bodies (hey, we celebrate ongoing relationships with other
people, what about ongoing relationships with our own bodies?, specifically:
- Start of menstruation.
- First gray hairs.
- Surgery. (Undergoing surgery via general anesthesia is like dying and being resurrected!)
- Ending or starting a job (sometimes there is recognition of *getting* a job but not so much around starting a job).
