In his Works and Days, the ancient Greek poet Hesiod recommended that a woman set up her loom and begin her weaving project on the twelfth day of the (lunar) month. The lunar month was counted from the first sight of the new moon, just as it is in the Jewish calendar, rather than from the astronomical dark of the moon as is modern scientific practice.
Accordingly, I have set 5 February of this year as my setup day, as 5 February is the next occurring twelfth day of a lunar month.
Today we got the loom wood. The clock is ticking!
