When

Some significant dates:

Stories about these dates will appear in the blog as time permits. Most dates listed here use the Gregorian calendar, though I enjoy using, and living by, the Hebrew calendar as much as possible. I do this not out of “nationalist” or “parochial” interests, though I’m certain they play some role. Rather, I do this because I like feeling both the solar and the lunar cycles in my life.
