Dalereckoning is taken from the Year of Sunrise, 1 DR, 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. In some texts, primarily those which do not have direct ties to Dales history, Dalereckoning is called Freeman's Reckoning (FR). The calendar is widely used in Faerûn but has not spread beyond its shores.

The Spellplague, called the Blue Breath of Change by the inhabitants of Abeir, was a disaster that struck Realmspace and even the planes themselves, caused by Mystra's assassination.

In 1487 DR, Thultanthar was brought to ground by Elminster Aumar. It fell upon Myth Drannor, destroying both cities.
