Luckily, birthdays seem to be about a year apart which seems about the right amount of time to be any one age. My year is marked also by three main holidays: Rosh Hashana, Chanukah, and Passover. There's a circularity about those holidays. They roll around about as often as birthdays. My family gathers round in varying numbers. There's usually a full moon. This year there will also be a total eclipse of the moon on Passover (April 4 - between Good Friday and Easter Sunday). Even though there's circularity and reoccurrence in the holidays of the year, we generally approach them in new ways as older people, but also as new and different people and more or less evolved from the previous year....so linear. If you don't evolve, there might be a divorce and you are left out of the celebrations and out of the family. The older members of the family get old and die. My siblings and cousins are now the older members of the family just as our parents were before us. I could be convinced that the linear is an illusion or perhaps a particularity within a larger circular eternity.What markers are special in your year? How do they prompt you to think about time? Do you experience it as an eternal round or a linear march?
My year is marked by birthdays - but there's a definite linearity about birthdays. One counts them only in one direction.
