What time does the ghost gate open in Mid-Autumn Festival?

The gate of hell opened in early July and closed on July 30. Mid-Autumn Festival is also called Ghost Festival. It is said that the first day of the seventh lunar month is commonly known as "opening the gate of hell". Then on the 30th, when the gates of hell were closed and the ghosts of hell returned to the deceased to reunite with their relatives, many homeless ghosts appeared. Ghosts without owners in the underworld will run to the dead and wander where people can find food. This is why we burn incense and paper money at July, because we want to avoid the resentment of these lonely souls. So in the seventh month of the lunar calendar, China used to call it Ghost Moon, which means that the door of the gate of hell is always open and closed, and ghosts can travel around the world. July 14 is the day when the gate of hell opens wide, which lasts until July 15, and then closes slowly until the gate of hell closes on July 30.
