Full year of October

**Full year of October** is a calendrical concept in which October is the only month of the year, so instead of October lasting for just 31 days, October last 365 days in common years or 366 days in leap years, meaning literally everyday is October. On this calendrical system, New Year's Day is October 1st, compared to January 1st on the Gregorian calendrical system we all use everyday, and granted there's no January in that single-month calendrical system.

Just like Gregorian calendar system, October-only calendar system are designated by years, but translated from the year exclusively used around the world. The names for the eras in that system for designating years are ONE, which stands for October Noir Era, and BONE, which stands for Before October Noir Era. Those two eras are analogous to CE (Common Era) and BCE (Before Common Era) in the Gregorian system. Currently, we are in the ONE era, which began with year 0 (in which it doesn't have on Gregorian calendar) on October 1, 2016 to coincide with the time when October Noir was forming, and during which the first album, *The Haunting and the Powerful* which came out on October 19, 1 ONE (2017), was in development. Using that single-month calendar system and using American-styled month-day-year, today is October 120, 7 ONE, in which the current year, 7 ONE, began on October 1, 2023 and will end on September 30, 2024. The last day of BONE was September 30, 2016, which translated to October 366, 1 BONE, and the very next day was October 1, 0 ONE. The final year of BONE lasted 366 days instead of 365 since 2016 was a leap year.
