The Jotnar Calendar

The realm experiences 5 seasons, three phases of winter and 2 of spring. Each season lasts for 119 days and is considered one-fifth of a year, a full year in Iotnheim is 595 days. The calendar is arranged by lunar cycles, known as mánirás; Iotnheim’s three moons chase each other over the course of 17 days, until they eclipse each other, significantly darkening the night sky and marking the beginning of the next lunar cycle. These mánirás were named after the Sjauhermaðr in honor of their victory over the Myklu Liðit some 200 years ago.

Historical Eras
A fierce debate raged across academia in the early fourth Era about just how to delineate the history of Fjalltin. Competing calendars led to conflicts both in written histories and more tangible issues like legal disputes, where conflicting dates created additional points of contention. The current era markers rose out of the works of the iconic Grippli biographer Gee Horo, who proposed using the population levels of the Jotunn as the boundary points for each Era.

The First Era was the birth of Iotnheim, often though of as the glory days of the Jotunn. No one knows the exact length of the 1st Era, a constant point of contention in academia. Horo proposed that the Second Era began with Ymir's passing and the rise of the mortal races. The second era lasted for close to a thousand years, ending only due to the mysterious decline of the Jotunn population. The 3rd Era began when the Jotun's numbers reached less than 100 known to be alive, the Third Era is known as the bloodiest and shortest era, spanning only 291 years. With the death of the last known Jotunn, Vreni Stormenska, in the final days of the Kornarok the Fourth Era began. As noted above, this era is in its 211 years.
