Definition: The term "blood moon" comes from a Jewish rite called Tannaim, which has been performed by priests since ancient times to purify the blood of sacrifices before they are slaughtered. It's often associated with the end of an old moon cycle or the beginning of a new one. In ancient times, it was believed that a "blood moon" would bring about the judgment on the earth and its inhabitants, as it signified the final days of the month of Tishri (the second month in the Hebrew calendar). However, this belief is now considered to be mythological and not based on scientific evidence. In modern times, blood moons have been observed by many people around the world. They are believed to represent a spiritual or divinely appointed time for cleansing or purification, as they often symbolize the end of old cycles or the beginning of new beginnings. Blood moons can also occur in conjunction with other significant events like weddings and funerals. While there is no scientific proof that blood moons actually occur, they have been observed by many people all over the world, serving as a reminder of the importance of good health and purification for those who observe them regularly.
