The ancient Junda were a tribal people living on a group of islands northeast of Anasthias. They were almost entirely dependent on the sea for their livelihood, and so rather than developing a solar calendar based on sowing seasons, their calendar was based on the semi-annual cycle of storms.

Despite their seeming lack of sophistication they were able to develop a complex mathematical system, using Base 6. Their annual calendar was based on the Great Tides, which occur when the world is in conjunction with the giant planet Kwato’or, the brightest star in the sky. The conjunction happens every 1.32 Helevos solar years, or every 546.74 days. Use of the calendar was sometimes imprecise, but the year always started when the Yending Star and Kwato’or aligned, so days were added ad hoc when the calendar and scale did not precisely align.

The start of the Solar and Storm year coincided every 33 solar years, or 25 storm years. This is 55(base 6) in the Junda’s number system, pictured as two hands outstretched. This is called a generation: the time taken for a man to grow, have a child, and have that child mature.

The longer-scale Junda calendar was measured by "ages", each age being six conjunctions: ie 125 storm years, or 198 solar years. An age was long enough for a family to rise and fall, from the birth of a man to the death of his last grandchild: three lifetimes. Years were numbered as to the current age, from 1 to 325(base 6).

The calendar was divided as follows:

1 Week = 6 Days
1 Month = 3 Weeks
1 Season = 5 Months +1 day (91 days roughly equals a solar season. The first week of each season starts with a day festival.)
1 StormYear = 6 seasons = 30 months = 546 days
1 Generation = 25 stormyears
1 Age = 6 generations

History

Because it measured by Ages, and because the Junda were relatively unconcerned with the passage of history or record-keeping except in oral tradition, it is impossible to know when the Stormscale began or how long it was used. Modern historians believe it to be very ancient, used probably throughout the current Aeon and possibly dating back thousands of years before.

However, the Stormscale went into decline when the Junda conquered the mainland and formed modern Harthera. Separated from their reliance on the sea, and more closely tied to agriculture and foreign ways, the Stormscale was used only in the home islands, and for traditional religious purposes. It was eventually abandoned in favour of a modified version of the old Saloyan calendar.
