A Saturday Moon

In Suffolk a new moon falling on a Saturday was said to bring bad weather for the month that followed, as the rhyme had it. Chambers’s correspondent worked out that Saturday moons came about twice a year, so that the warning showed a want of observation. Other moon signs there were more hopeful: to see the old moon in the arms of the new was a sign of fine weather, and so was the new moon with its horns turned up, for then it held the water supposed to be in it, which would run out if the horns turned down.
