William March, which shares the etymology of Mars and is also related to the military, “March!”, as this is the time of year when war traditionally began, has been a harbinger in many cultures. I’ve been recently acquainted with Hyakki Yagyō (百鬼夜行, “Night Parade of One Hundred Demons”), associated with this time of year. If anyone knows more about this, please inform.
