Here is the table I made correlating the info:
The order is as follows:
The middle of Ral’s Rest falls on High Sun, or the first day of the year. Dominary 1.
All are 75 days long.
Flamesky starts on the exact midpoint of the year. Low Sun. Which is also day 1 of Sun Ascending, or Morrow 3 on the Merchant calendar. I’ll get a graphic up to help explain it.
I am also noticing that my table is not lining up with what the author used for the day numbers assigned to the sign months. But my table is consistent with the months presented in Ivory Triangle and the Merchant Calendar. It’s possible he is ignoring the “on the cusp” days in the zodiac and assigned those to a sign instead on their own 5 days.
I started working to try to figure out if that was the case, but my laptop battery died and I don’t want to go get the charger out of my car.
I was able to locate a copy of a draft of Lost Cities on the DS Facebook page. It has the same information that @Bdmdragon so generously provided above.
The problem with the info in there I have is that it incorrectly assumes Low Sun is the beginning of hot season in the year and not High Sun. It incorrectly sets Low Sun as when flamesky starts. Which is consistent with how I made my graphic. But other DS resources place high sun as the beginning of the hot season or summer. Which is why my graphic also shows the “normal” four seasons seemingly contradict.
In the copy I found, with a date of possible 2017 from its last update, It says on pg 54
“ Low Sun corresponds to Low Sun on the Merchant’s Calendar. True to its name, this first day of Flamesky is the hottest and longest day of the year, and there is no wind. Not even bandits roam the Trembling Plains on Low Sun, although they sometimes make one last raid immediately afterward, in early Flamesky. In Kurn, Azeth’s Rest, and the entrenched camps in the badlands outside the Trembling Plains where some herders have holed up for Flamesky, no one works except for the watchmen. Those who have sufficient water, drench their clothes in an effort to survive the heat. No one sleeps the night before Low Sun; there is music and dancing, and for those who can afford it, broy that has been kept buried deep in the ground, just for this occasion. They celebrate because the night may be their last; more elderly Eloy die on Low Sun than on the rest of the days combined, because of the heat.”
The low sun point should be the winter solstice and the high sun the summer solstice. Additionally although high sun wouldn’t be the hottest day, just be day the sun is highest in the sky, marking the beginning on the hottest season. the planet would continue to heat up over the next several weeks. Like on Earth June (20-21) is the first day of summer, longest day of the year, and summer solstice. The hostess days aren’t for another month or so.
I think this can all be corrected by just changing the references that mention Low Sun to High Sun. I would also change the phrase:
this first day of Flamesky is the hottest and longest day of the year,
this first day of Flamesky is the longest day of the year and marks the beginning of the hottest days of the year,
This would all be consistent with how the Info in Ivory Triangle is presented. This will cause the need to check for discrepancies in the the other seasons mentioned and for the days on which they begin and end.
