The calendar of Harptos

The world of the Forgotten Realms uses the Calendar of Harptos, named after the long-dead wizard who invented it. Each year of 365 days is divided into twelve months of thirty days each. Each month is divided into three tendays. Five special holidays fall between the months and mark the seasons. Another special holiday, Shieldmeet, is inserted into the calendar after Midsummer every four years.
