I have just started my new campaign in the Great Dale. I am running the exploration of a large crypt and as a puzzle I want to do something with dates in Faeruns history, but I am unsure as to what Calendar to use. SO what I want to know is what dating system would have been in use in Impiltur during the reign of Bellodar I known as the Conqueror, who ruled from 562DR to 588DR.
"These things also I have observed: that knowledge of our world is to be nurtured like a precious flower, for it is the most precious thing we have. Wherefore guard the word written and heed words unwritten and set them down ere they fade . . . Learn then, well, the arts of reading, writing, and listening true, and they will lead you to the greatest art of all: understanding." Alaundo of Candlekeep
