Wolf, an eclipse doesn’t accur at every Molad. There is also a 5 degree deviance to take into account.
That’s absolutely correct. However, when an eclipse does happen, it can only happen at the molad.
That’s why eclipses are important for the ancients in determining the length of a lunar month. You can’t tell when the molad actually happens — the moon is usually not visible for hours (or even a day) after the conjunction. The only way to know *for certain* when a conjunction happens is by viewing a solar eclipse. Without an eclipse, you don’t know for certain which when the conjunction occurred.
