Ginkgo Day magic

A blogger writes: "The Ginkgo tree (usually) loses all (or the vast majority) of its leaves on one day. This day is Ginkgo Day, the only holiday I know of where the determination of the date is independent of any human decision. The tree decides, and Ginkgo Day may be different from town to town, or even from tree to tree within a given town. The tradition I started (and I really don’t like saying that) is that if you catch a falling leaf on Ginkgo Day, it brings good luck. Oh, and you can catch leaves for other people–giving them the leaves will bring luck to them. “Dr. K.” Several years ago (but well after the tradition had momentum) I caught many leaves, and happened to give one to “Dr. K.”, a colleague of mine who had passed by and asked me what I was doing. Dr. K. had recently been through a divorce, and thought she could really use some luck. Well…within the next week or two, she had met a man, a very nice man, an English teacher. She credited the ginkgo leaf. No, really. She told him about it, and gave him that same ginkgo leaf, laminated into a bookmark. A few months later, he carefully cut the leaf out of the bookmark, and presented it to her in a poem he had written, in which he proposed marriage. Of course, she accepted, and credited the ginkgo leaf. I have a copy of a poem he read at the wedding, crediting the ginkgo for their meeting and love. (The final copy, framed with that same leaf, is on the wall in their house.) The wedding cake had green ginkgo-leaf frosting; she wore gold ginkgo-leaf earrings. One of their wedding gifts was a set of crystal goblets etched with ginkgo leaves. In subsequent years, I would see her at the tree on Ginkgo Day, catching leaves for friends. “I really do believe in this!” Two years ago, she moved out of state. At her new house, of course, they have planted a ginkgo tree. "
