This division influences how we structure our schedules and plan activities throughout the day. Additionally, the use of twelve in calendars helps organize human life by dividing the year into manageable segments.
Twelve also appears frequently in literature and storytelling. Fairy tales often involve tasks or challenges that must be completed in multiples of twelve, reflecting the idea of overcoming great odds to achieve success.
