I was looking in the Farmers Almanac to check on vegetable planting dates and came across the best days to brew. This month, April, the 26-27 are the best days to brew. They go by phases of the moon. This got my interest because I used to work in a construction type job where we would be digging water lines, mains, fire hydrants etc. At certain lunar phases all the dirt would fit back and other times not. At least that what the Old Timers told me.
