Timeline of Jijo - David Brin's Uplift Universe

This page contains spoilers about Brightness Reef and Infinity's Shore. Those who haven't read those books and plan to read them should exit immediately. I will refer to these books by their initials, BR and IS.

This page is under construction. Help would be greatly appreciated.

The official David Brin site is www.davidbrin.com, and it includes samples of the books. The complete Uplift timeline can be found at Stewart Blandón's site or at Trent Shipley's site

I am also building an Uplift timeline, that is more "canonical" than the above timeline, since mine is based on the books.

Units of Time

Many different time units are used in the Uplift Storm Trilogy. I will try to summarize them: These units can be related by: Using the above relations as starting points and doing some lenghty computations based on the books, it's possible to conclude that:

Timeline, by days

I still can't fit all events into a unique timeline, because there are too many ambiguities. For example, if we follow Sara from the day she left Dolo Dam to the day she arrives in Mount Guenn, it seems that only a few days have elapsed. But this period corresponds to the date of the arrival of the Rothen until two days after the Battle of the Glade, and (in other characters' accounts) this period is months long! So, we must assume that Sara spend a long time in Tarek Town and in Biblos!

The errors that are obvious are marked in Red with the suggested correction in Green . Deductions are in Blue .

I decided to break the timeline into five sets, each set, internally, with fixed dates.

Reference: arrival of the Rothen

Book reference Day Hour Event Loocen Torgen Passen
BR II. Asx 0 noon The Rothen/Danik ship lands in the Gathering Glade      
BR II. Sara 1 00:00 or so Meeting in Dolo Dam rising    
BR IV. Sara 1 dawn Sara et al leave Dolo Dam in ship Hauph-woa
down river Roney
BR IV. Sara 1 sunset Ship Hauph-woa reaches Unity Point      
BR IV. Sara 2 00:00 +/- some hours River Roney lit by two moons not visible visible visible
BR VI. Sara 2 morning Ship Hauph-woa is ambushed in Bing Village      
BR VIII. Sara 2 mid-afternoon Ship Hauph-woa reaches Canyon Country      
BR X. Sara 2 late afternoon Concert in ship Hauph-woa to celebrate The Stranger's recovery      
BR X. Sara 2 almost nightfall Ship Hauph-woa arrives in Tarek Town      

Reference: Robot Battle in One-of-a-Kind's Lair

Some events of this partial timeline overlap the events of the above timeline. However, I can't get an exact correlation between the two.

My Hypotheses

Loocen lower than Torgen ?

All the books refer to Loocen as the first and Torgen as the second moon; I guessed that this was size and distance from Jijo. This has to be checked against the books.

Jijo Month = Loocen Synodic Month ?

Using the fact that Asx refers to the date of the Rothen arrival as
It was springtime, early in the second lunar cycle of the nineteen hundred and thirtieth year of our exile-and-crime, when the Rothen arrived, manifesting unwelcome in our sky. (...)
(BR, II. Book of the Slope, Asx), together with a statistical overlap of my estimations of a Jijo Month and Loocen's synodic period, I supposed that a Jijo Month were the period from a New Loocen to the next New Loocen.

However, this hypothesis can be easily disproven. Early in a lunar synodic month means that the Moon is Waxing Crescent, or that the Moon sets during the night (soon after New Moon it sets soon after sunset; and just before Full Moon it sets just before sunrise; but it never rises during the night - see The Moon: an Introduction for more details about the phases of the Moon). But in Chapter II Dwer, at the time Rety steals his bow, he observes Loocen over sillouetted peaks before dawn, and in Chapter II Sara there is a meeting in the night after the Rothen arrival, and Loocen rises during this meeting

Using an other origin for Loocen's Month still can't give the correct number of days per month, because Loocen Synodic Month is too small.

Jijo Month = Torgen Synodic Month ?

I tested this hypothesis hoping that it would not be true; Torgen is the second moon (probably only in brightness but not in distance from Jijo), and there's no reason it would be chosen as the month reference.

Alas, I guess I can disprove it with a reasonable certainty: from the tables, above, notice three Torgen risings from the period from midnight to dawn; these three risings are set apart by at least 5 days (see BR p.543, IS p.38, and IS p.503), later when I find time to write what I calculated O:-)

Preliminary Numbers:

The Timeline

This timeline uses Jijo units of Time. When a date in Earth units is more accurate than the date in Jijo units, I will give it. Otherwise, chech my Brin Timeline.

Like my other timelines, I will put some arrows to help the reader follow some characters. However, I decided to represent uncertainty by a color code, from green, representing a direct quote from the canon, to red, when the canon can only give an approximate date. Or: Error > 1000 Years, Error 100-999 Years, Error 10-99 Years, Error 1-9 Years, Exact Year.
