BSW has its own calendar, which starts on the "Day the Great Oracle Appeared". It consists of four seasons: Lenzing (which is similar to our world's spring), Ernting (summer), Gilbhart (autumn) and Hartung (winter). Each season has a length of precisely 60 days, therefore a BSW year takes 240 days. You can see the current day by using the World Map tool.
The quantities of raw material types given by each game depends on the BSW calendar. The number of raw materials produced remains the same, however, the types and quantities change. Only the Quarter Master knows the exact type given.
