The point of a year is to seize hold of a large enough chunk of your life so that even when you're an old lady that chunk stands out in your memory. The point of a year is also to make something of your own a priority long enough to really make a dent in it or resolve it or complete it. So there's nothing sacred about the exact time span of 365 days. But feeling that you're worth something like a year that is sacred. The Rhythm of Your Life Working within the rhythms of time that too is sacred.
Women have a special relationship with time.
Menstruation, aging, birthdays, the biological clock, the ceremonies for which we feel responsible all these give us an unusual awareness of time. Time as something to treasure, time as a resource, time as the arena in which we live our lives. We focus too much on time as the enemy aging, for example. On time as the scarcest of resources our feeling incredibly busy, for example. But more than anything we're used to flowing with the river of time.
