There were two folkloric stories about how this barrio got its name. One said that it was from “haya,” a “heap of harvested or sun-dried palay (rice).” The other said it was from “panghaya,” supposedly the act of preparing to strike with a bolo during a duel. The barrio’s original settlers were the Rabano, Panganiban, Sumagpang and Pasia families. During the Philippine Revolution, some of the barrio’s men joined the Katipunan. In 1901 or 1902, inhabitants of the barrio were forced by the US Army to live in concentration camps. In World War II, Panghayaan was the hideout of a guerilla unit under the command of one Sixto Guerra, supposed to be a famous guerrilla leader.
Panghayaan is situated at approximately 13.7715, 121.1750, in the island of Luzon. Elevation at these coordinates is estimated at 136.4 meters or 447.5 feet above mean sea level.
