1. Dead Time, a.k.a. Dead Hour, Devil's Hour, the Wolf Hour, is the time from 3:00 AM to 4:00 AM. At this time it is believed that spirits and demons are most active. This belief stems from the lore of Jesus being crucified at 3:00 PM. Since this would be a holy time for Christians, then the Satanic perversion would be the opposite, at 3:00 AM. According to folklore or urban legend, this hour is also believed to be the time that most nocturnal deaths occur.
2.) Dead Time, a.k.a. Dead Hour, is a time deemed most appropriate for magic as claimed by Minerva, the Voodoo priestess who was featured in the book, Midnight In The Garden Of Good And Evil. According to Minerva, Dead Hour is 11:30 PM to 12:30 AM. The first thirty minutes are for doing good work and the last thirty minutes are for doing evil work. Additionally, Minerva claimed that Dead Hour is the most appropriate time for gathering graveyard dirt for use in spells.
