Dragonreckoning

Dragonreckoning (also known as Dalereckoning or DR) is the method by which the world of Abeir marks the years on the Calendar of Harptos.

Year Marker
Dragonreckoning is taken from the end of the Amra empire and the rise of the Sword Lands in the southeast of Laerakond. This would be the catalyst for the rise of more human empires in Laerakond. The dragonheirs lords of Amra would spread out across the southeastern parts of Laerakond. This would lead to the creation of Eskorn which would assist Tymanchebar in its bid for independence from Skelkor. These events are largely seen as a herald of the end of the Rule of Dragons, hence the name Dragonreckoning.

Use of Dalereckoning
At the same time in Toril, DR has different terminology known as Dalereckoning. The term is taken from the Years of Sunrise, when the Standing Stone was raised by the elves of Cormanthyr and the human Dalesfolk. Since this time, humans were permitted by the Elven Court to settle in the more open regions of the forests.
