Dan Mask Blacktime Series Bracelet

The Dan people of West Africa have a unique calendar system that is still in use today. The Dan calendar is a lunar calendar, which means it is based on the cycles of the moon. It consists of twelve lunar months, each lasting approximately 29.5 days. 

The Dan calendar is used to mark important events in the community, such as planting and harvesting seasons, as well as religious and cultural festivals. The calendar is also used to determine the date of important ceremonies, such as initiations and weddings. 

The Dan calendar has a unique feature known as the "invisible month." This month is added to the calendar periodically to keep it in sync with the solar year. The addition of the invisible month ensures that important events, such as the solstices and equinoxes, occur at the same time each year. 

The Dan calendar is also notable for its use of a 7-day week. Each day of the week is associated with a particular deity or spirit, and certain activities are believed to be more auspicious on certain days. For example, Thursday is associated with the deity Gunu, and is considered a good day for planting crops. 

Overall, the Dan calendar is an important part of the cultural heritage of West Africa, and is still used today as a way of marking important events and organizing communal life.
