==Notes==
*In a preview for the Hazbin Hotel pilot, the Royal Family portrait is taken in 1871;HAZBIN HOTEL- "LET'S MISBEHAVE" -(CLIP)- NOT FOR KIDS (Royal Family portrait) in addition, the year 1981 was seen in the Helluva Boss Pilot as the year Imp City was established. These imply that Hell uses Gregorian years, however, as both were details of early versions of each series, it is unknown if these are accurate to the current timeline.
*In "Seeing Stars", a coin that Moxxie picks up is printed in the year "2021", implying the current or prior year that Azathoth's Tears takes place.
