Reckoning · The Twelve Months

The Calendar of Aeon

Twelve months, seven days, one turning year.

The year in Mar de Oro is divided into twelve months of the same lengths kept on Earth, spanning 365 days in a common year. Each month is named for its position in the reckoning — Primus the first, Secundus the second, and so on — a habit inherited from the old scholarly tongue and still used on charter, ledger, and log.

The week runs seven days, from Prima to Septima. Sailors, factors, and clerks across the Golden Sea share the same week even when they disagree on almost everything else.
