Forgotten Realms has a long and detailed story. To this we add our own adventures. This will be used as potential background for the campaign, but don’t stress about it if you don’t like delving into fictional histories. It’s here purely for your enjoyment. Anything vital to the game will be treated as fully as is required at the table, no homework necessary.

The Forgotten Realms Wiki and The Grand History of the Realms provide excellent resources for this. However note that any given canonical events in the Forgotten Realms world are not necessarily part of this setting.

Calendar of Harptos

The most commonly used date system in Faerûn is is the Dalereckoning (DR). The Dalereckoning is counted from the Year of Sunrise, when the Standing Stone was raised by the elves of Cormanthyr and the human Dalesfolk.

Within a single year, Faerûn is largely unified in using the Calendar of Harptos. It consists of 365 days, split into 12 months of 30 days each. This leaves 5 leftover days, which are considered to be special holidays that fall between particular months. Each month consists of 3 weeks of 10 days, referred to commonly as a tenday.

The months (and the special holiday days) are:

  • Hammer (also known as Deepwinter)
  • The Midwinter holiday lies between Hammer and Alturiak.
  • Alturiak (also known as “The Claw of Winter” or “The Claws of the Cold”)
  • Ches (also known as “The Claw of Sunsets”)
  • Tarsakh (also known as “The Claw of the Storms”)
  • The Greengrass holiday lies between Tarsakh and Mirtul
  • Mirtul (also known as “The Melting”)
  • Kythorn (also known as “The Time of Flowers”)
  • Flamerule (also known as “Summertide”)
  • The Midsummer holiday lies between Flamerule and Eleasias.
  • Shieldmeet occurs the day after Midsummer, once every four years.
  • Eleasis (also known as “Highsun”)
  • Eleint (also known as “The Fading”)
  • The Highharvestide holiday lies between Eleint and Marpenoth.
  • Marpenoth (also known as “Leafall”)
  • Uktar (also known as “The Rotting”)
  • The Feast of the Moon holiday lies between Uktar and Nightal.
  • Nightal (also known as “The Drawing Down”)

Alternative Date Systems

Alternative date systems in Faerûn include:

  • A list of names for each year supposedly first written by Augathra the Mad. They go from -422 DR to what will be 1600 DR (The Year of Unseen Enemies).
  • The Northreckoning (NR) dates from the year Ahghairon became the first Lord of Waterdeep. Waterdeep’s importance in trade up and down the Sword Coast has made this the most popular means of counting years in the region, though there have always been some who have considered this the height of Waterdhavian arrogance.
