Two of the Roman holidays held during this month were July 8 - 9 when the Goddess Juno was honored and the Neptunalia on July 23, when Neptune, the god of the seas and earthquakes, was placated.
In Japan, the Full Moon of July saw the O-Bon, or Festival of Lanterns. This was a combination of Buddhist and Shinto beliefs that honored the dead. Homes, tombs, and ancestral tablets were thoroughly cleaned. Altars and shrines were decorated. The gardens were hung with lanterns to light the way of the dead so that they could join with their families for the three-day ceremony.
The Egyptian New Year fell in July, as did the Opet Festival, which commemorated the marriage of Isis and Osiris. Their sexual union was said to bring good luck to all people. About the same time in Rome, the love of Venus and Adonis was celebrated. The Egyptian year was measured against the Nile and its yearly fertile floods. This was also the time of the birth of Isis and Nephthys, Osiris, Set, and Haroeris. These days were the ones won by Thoth for these deities; births; in other words, there were the necessary days to make the solar and lunar calendars match.
The Incas had a ceremony called Chahua-huarquiz, Chacra Ricuichi, or Chacra Cona, which meant Plowing Month. While the Northern Hemisphere was beginning its agricultural harvests with the reaping of the corn crop, the Southern Hemisphere was just beginning to break ground for planting.
Buddha's Birth and Preaching, also called the Picture Feast, was celebrated in Tibet.
