  1. Dune, Appendix II, page 543. "Mankind's movement through deep space placed a unique stamp on religion during the one hundred and ten centuries that preceded the Butlerian Jihad." The Jihad was 201-108 BG, so this would approximately be 11,100-11,200 BG.
  2. Chapterhouse: Dune, page 33. "The society she had in mind had supposedly died out shortly after the Second Interspace Migrations." The name "Second Interspace Migrations" implies a wave during the very early period of space travel, which began in 1960 or 11200 BG. So circa 11000 BG or 2160.
  3. Children of Dune, page 33. The date of c. 5000 BG is attained from another broadly guessed date, that of the discovery of the spice c. 1000 BG, when Arrakis must already have become a desert.
  4. Dune, Appendix II. "The major dams against anarchy in these times were the embryo Guild, the Bene Gesserit and the Landsraad, which continued its 2,000 year record of meeting in spite of the severest obstacles." The time referred to is the period after the end of the Butlerian JIhad in 108 BG. 108 + 2000 = 2108, rounded to 2100.
  5. Dune, Terminology of the Imperium: ZENSUNNI. "followers of a schismatic sect that broke away from the teachings of Maometh (the so-called "Third Muhammed" about 1381 B.G."
  6. Children of Dune, page 18. "spice of Arrakis (Dune) with geriatric properties first noted by Yansuph Ashkoko, royal chemist in reign of Shakkad the Wise." The spice must have already been discovered by the times after the Butlerian Jihad, which produced the spice-dependent Bene Gesserit and Spacing Guild. Therefore, a date of approx. 1000 BG is likely, but far from certain.
  7. Dune Messiah, page 235
  8. 8.0 8.1 Dune, Terminology of the Imperium: JIHAD, BUTLERIAN. "...begun in 201 B.G. and concluded in 108 B.G."
  9. Dune, Appendix II: The Religion of Dune, page 544
  10. Dune, Terminology of the Imperium: RICHESE
  11. Dune, Terminology of the Imperium: BENE GESSERIT. "the ancient school of mental and physical training established primarily for female students after the Butlerian Jihad destroyed the so-called "thinking machines" and robots." Chapterhouse: Dune, page 34. "We did not disturb the situation until I, Mother Superior during and after the battle of Corrin..." Therefore, the Sisterhood was formed at some time between the end of the Jihad (108 BG) and the Battle of Corrin (88 BG). So, circa 98 BG.
  12. Dune, Terminology of the Imperium: CORRIN, BATTLE OF. "The space battle from which the Imperial House Corrino took its name. he battle fought near Sigma Draconis in the year 88 B.G. settled the ascendancy of the ruling House from Salusa Secundus."
  13. Dune, Appendix IV, VLADIMIR HARKONNEN. "Vladimir Harkonnen is the direct-line male descendant of the Bashar Abulurd Harkonnen who was banished for cowardice after the Battle of Corrin."
  14. Chapterhouse: Dune, page 35
  15. Chapterhouse: Dune, page 243.
  16. God Emperor of Dune, page 180. "You think a man designed the first Guild ship? Your history books told you it was Aurelius Venport? They lied. It was his mistress, Norma. She gave him the design along with five children."
  17. Dune, Appendix II
  18. Dune, Terminology of the Imperium: ORANGE CATHOLIC BIBLE
  19. Dune, Terminology of the Imperium: GUILD
  20. Dune, Appendix II, page 549. "The Azhar Book traces this statement to the first century religious writer, Neshou; through a paraphrase."
  21. Dune, page 487. "The language of the Great Convention is clear enough: 'Use of atomics against humans shall be cause for planetary obliteration.'"
  22. Dune, Terminology of the Imperium: GREAT CONVENTION
  23. Dune, Terminology of the Imperium: ASSASSINS’ HANDBOOK
  24. In Children of Dune, we learn that the laza tigers were brought to Salusa in the 2200s - so the change in the capital happened before this date. It probably happened not too long after the court was removed to Kaitain, so this event is placed at circa 2000 in this timeline.
  25. Children of Dune, page 18. "They were called Laza tigers, a special breed brought here to the planet Salusa Secundus almost eight thousand years past."
  26. Dune, page 385. "And she saw the thread of the past carried by Sayyadina after Sayyadina - first by word of mouth, hidden in the sand chanteys, then refined through their own Reverend Mothers with the discovery of the poison drug on Rossak..."
  27. 27.0 27.1 27.2 27.3 27.4 Dune, page 40. "YUEH (yü’ē), Wellington (Weling-tun),S trd 10,082-10,191; medical doctor of the Suk School (grd Strd 10,112); md: Wanna Marcus, B.G. (Stdrd 10,092-10,186?)..."
  28. 28.0 28.1 Dune, Appendix IV: VLADIMIR HARKONNEN. "(10,110-10,193)..."
  29. Dune, page 4. "...the Harkonnens had been on Arrakis for eighty years, holding the planet in quasi-fief under a CHOAM Company contract to mine the geriatric spice, melange." 10,191 - 80 = 10,111.
  30. Dune, page 1. Paul was born in Shaddam's 57th year. 10176 - 57 = 10119.
  31. 31.0 31.1 Dune, Appendix IV, COUNT GLOSSU RABBAN. "(10,132-10,193)..."
  32. 32.0 32.1 Dune, Appendix IV, COUNT HASIMIR FENRING. "(10,133-10,225)..."
  33. 33.0 33.1 Dune, Appendix IV, SHADDAM IV. "(10,134-10,202)...". However, a birth date of 10134 conflicts with other statements about his age made by the Princess Irulan, and a much more likely birth date for Shaddam is 10119 (see Reference 29), and that Shaddam could not have died in 10202 either due to him still being alive in Dune Messiah. This puts the dates of the Almanak en-Ashraf into doubt.
  34. 34.0 34.1 Dune, Appendix IV, LETO ATREIDES. "(10,140-10,191)..."
  35. 35.0 35.1 Dune, Appendix IV, LADY JESSICA. "(10,154-10,256)..."
  36. Children of Dune, page 99
  37. Dune, page 250
  38. 38.0 38.1 Dune, Appendix IV: SHADDAM IV. "...reigned from 10,156 (date his father, Elrood IX, succumbed to chaumurky) until replaced by the 10,196 regency set up in the name of his eldest daughter, Irulan."
  39. Pardot tells the Fremen that it will take 350 years for Arrakis to become a paradise in Appendix I. We know from Children of Dune that this is achieved c. 10500. 10500 - 350 = 10150. In Dune, Liet has been Imperial planetologist for some time, as indicated not only by the end of Appendix I but the fact that he has had enough time to become something of a religious figure among the Fremen. An estimate of fifteen years would put his father's death at 10175 and his birth at 10156, which matches with the Children of Dune calculation as Liet must have been born, early, because of his age in dune, but not too early, because he was already a teenager when his father died, in Pardot's time with the Fremen.
  40. Dune, page 46. "The Harkonnens have been stockpiling for more than twenty years." 10,191 - 20 = 10,171.
  41. Dune, Appendix IV: SHADDAM IV. "Appropriations for Sardaukar training went down steadily in the final thirty years before the Arrakis Revolt." 10,193 - 30 = 10,163.
  42. Dune, page 7. "The Lady Jessica was my serving wench, lad, for fourteen years at school." 10,154 + 14 = 10,168.
  43. Dune, Appendix IV: LADY JESSICA. "She graduated from the Wallach IX B.G. School."
  44. Dune, page 12. "His mother had undergone this test."
  45. Dune, page 345. "On his seventeenth birthday, Feyd-Rautha Harkonnen killed his one hundredth slave-gladiator in the family games." 10,191 - 17 = 10,174.
  46. Dune, page 107. "She's been with me for sixteen years!" 10,191 - 16 = 10,175.
  47. Dune, Appendix I. "By this time his son, Liet-Kynes, was nineteen, a full Fremen and sandrider who had killed a hundred Harkonnens." Due to the estimated date of 10156 for Liet's birth, Pardot would die in 10175.
  48. Dune, Appendix IV: SHADDAM IV. "His wife, Anirul, a Bene Gesserit of Hidden Rank, died in 10,176."
  49. Dune, page 114. "My father [Shaddam] was 71 at the time and looking no older than the man in the portrait, and I [Irulan] was but 14..." 10119 + 71 = 10190. 10190 - 14 = 10176.
  50. Dune, page 3. "Do not be decieved by the fact that he was born on Caladan and lived his first fifteen years there." 10,191 - 15 = 10,176.
  51. 51.0 51.1 Dune, page 376. "...learning then that Kaleff, the elder of the two, was ten, and the natural son of Geoff. Orlop, the younger, was eight, the natural son of Jamis." 10,191 - 10 = 10,181. 10,191 - 8 = 10,183.
  52. Dune, page 62. '"We've known each other six years," she said.' 10,191 - 6 = 10,185.
  53. Dune, page 404. "The Padishah Emperor turned against House Atreides because the Duke's Warmasters Gurney Halleck and Duncan Idaho had trained a fighting force - a small fighting force - to within a hair as good as the Sqardaukar. Some of them were even better. And the Duke was in a position to enlarge his force, to make it every bit as strong as the Emperor's."
  54. Dune Messiah. "This had been a woman of about twenty years..." 10,209 - 20 = 10,189.
  55. Dune, Appendix IV: LADY ALIA ATREIDES. "(10,191-)..."
  56. 56.0 56.1 56.2 Appendix IV states that both Leto died and Alia was born in 10,191. Alia was born eight months after Leto died. Part II ends in mid-Autumn, which is late October or early November. Alia has still not been born at this point. Early in Part III, Alia is stated to be about two years old. ("Behind Harah came Alia, a girl-child of about two years.") We also know that it is still 10,193 at the end of Part III, due to Appendix IV. It seems unlikely that Part III covers just a month, so we can assume that Alia was born in November 10,191, and Part III picks up around November 10,193, probably ending in December. This would place the Siege of Arrakeen and Duke Leto's death in March 10,191.
  57. Dune, page 404. '"Rabban killed six thousand of them last year alone!" Still, Hawat stared at him. "And the year before it was nine thousand,"...'
  58. Dune, page 528. "It'll begin with Stilgr as Governor of Arrakis, but that can wait."
  59. Dune Messiah, page 4. "Muad'dib's Qizarate missionaries carried their religious war across space in a Jihad..."
  60. Dune Messiah, page 61. "'So we've spent ten years of negotiation for nothing,' Irulan said."
  61. Children of Dune, page 83. "Tyekanik, fresh from a savage argument with Farad'n's mother, glanced sidelong at the Prince, noting how the lad's flesh was firming as he approached his eighteenth birthday." 10219 - 18 = 10201.
  62. Children of Dune, page 188. "Wensicia found herself reminded of his [Farad'n's] death father. Dalak had been like that at times, very inward and complex, difficult to read. Dalak, she remined herself, had been related to Count Hasimir Fenring, and there'd been something of the dandy in both of them."
  63. Children of Dune, page 292. "You've lived eight more years than this flesh of mine." 9 + 8 = 17. 10219 - 17 = 10202.
  64. Children of Dune, p. 66, "A youth of perhaps fourteen standard years..."
  65. Dune Messiah, page 27. "Paul stared down at his own body: hard muscles, slender...a few more scars, but essentially the same despite twelve years as Emperor." 10196 + 12 = 10208.
  66. Dune Messiah, page 111. "flick - (the Jihad's recent Sembou victory would bear on Edric's action) - flick". This scene takes place in late 10208 at the end of the Jihad. The "recent" victory was probably slightly earlier that same year.
  67. Dune Messiah, page 118.
  68. Dune Messiah, page 289. "'Yes - she helped whip those soft Naibs into line. They take her orders now...as I do.' 'What orders?' 'She commanded the execution of the traitors.' 'Oh,' Idaho suppressed a feeling of vertigo as he looked up at the promontry. 'Which traitors?' 'The Guildsman, the Reverend Mother Mohiam, Korba...a few others.' 'You slew a Reverend Mother?' 'I did. Muad'dib left word that it would not be done.' He shrugged. 'But I disobeyed him, as Alia knew I would.'
  69. Dune Messiah, Excerpt from the Death Cell Interview with Bronso of Ix. "But the argument of the conspiracy came before my Analysis. Twelve years of Muad'dib's Jihad created the argument. That's what united the ancient power groups and ignited the conspiracy against Muad'dib." So, at some point after 10210.
  70. Children of Dune, page 29. "Leto sat playing a small baliset which had been sent to him on his fifth birthday by that consummate artist of the instrument, Gurney Halleck." 10210 + 5 + 10215.
  71. Children of Dune, page 29. "He sensed the absolute idealized summation within himself which knew how to play this baliset; though nine-year-old muscles had not yet been conditioned to that inner awareness." 10210 + 9 = 10219.
  72. Children of Dune, p. 142. "The next Landsraad session is almost two standard years away".
  73. Children of Dune, page 410. "Within one hundred years, there'll be fewer than fifty worms, and those will be sick ones kept in carefully managed reservations." 10219 + 100 = 10319.
  74. Children of Dune, page 412. "Oh, the worms will come back. All will be dead within two hundred years, but they'll come back." 10219 + 200 = 10419. "within", so rounded to 10400.
  75. Dune, Appendix I, "three hundred to five hundred years".
  76. God Emperor of Dune, page 151. "Quite early in his [Leto's] ascendancy he had revealed to the Ixians the exact location of the supposedly secret Ixian Core, the heartland of the technological federation which they governed." The approximate date of 10500 is taken from Leto's statement that this was quite early in his ascendancy, which began in 10219.
  77. God Emperor of Dune, page 13. "This planet of Arrakis from which I direct my multi-galactic empire..."
  78. God Emperor of Dune, page 359. "The wind called sandblaster has not been seen on Arrakis for some twenty-five hundred years." 13,728 - 2,500 = 11,228.
  79. God Emperor of Dune, page 170. "There've been no smugglers for almost twenty-five hundred years." 13,728 - 2,500 = 11,228. Taking into account the word "almost", we round this up to 11,230.
  80. God Emperor of Dune, page 72. "As has been observed by our investigators over the preceding two thousand years, the homogenization of family life continues unbated." 13,728 - 2,000 = 11,728. Rounded to 11,700.
  81. God Emperor of Dune, page 67. "Sister Cheoneh and Tawusko have returned safely from Arrakis to report confirmation of the long-suspected execution of the nine historians who disappeared into his Citadel in the year 2116 of Lord Leto's reign." 10,219 + 2116 = 12,335.
  82. God Emperor of Dune, page 258.
  83. God Emperor of Dune, page 158. "The Ixians operated in the terra incognita of the creative invention which had been outlawed by the Butlerian Jihad. They made their devices in the image of the mind - the very thing that had ignited the Jihad's destruction and slaughter. That was what they did on Ix and Leto could only let them continue."
  84. God Emperor of Dune, page 64. "Let me see, Leto thought. Moneo will be one hundred and eighteen years old in the week after our return from Onn." 13728 - 118 = 13610.
  85. Since the Ixians grew Hwi Noree in their no-room in the year 13702, it is safe to approximate they invented the technology around 13650.
  86. God Emperor of Dune, page 1. "We believe we are looking at the first Ixian Globe, the no-room from which all such devices evolved." Thus, it would be built around the same time as the technology for Hwi's was developed.
  87. God Emperor of Dune, page 18. "This Duncan feared that he was being replaced after almost sixty years of service." 13,728 - 60 = 13,668. "almost", so rounded to 13,670.
  88. God Emperor of Dune, page 127. "Footnote: Sister Quintinius Violet Chenoeh died in the fifty-third year of her Sisterhood, the cause being ascribed to melange incompatibility during her attempt to achieve the status of Reverend Mother." 13,728 - 53 = 13,672.
  89. God Emperor of Dune, page 153. "I guess I'm about twenty-six."
  90. God Emperor of Dune, page 67. "The following assessment of the state of the Empire in the year 3508 of the reign of the Lord Leto is taken from The Welbeck Abridgement." 10219 + 3508 = 13728.
  91. God Emperor of Dune, page 118. "Within three hundred years, the sandworm once more will reign here It will be a new kind of sandworm, I promise you. It will have animal awareness and a new cunning." 13,728 + 300 = 14,028.
  92. Heretics of Dune, page 41. "Teg was still a regal figure, tall and with that large head topped by grey hair. He was, she knew, four SY short of three hundred." 300 - 4 = 296. 15,229 - 296 = 14,933.
  93. Heretics of Dune, page 71. Teg recalls a time when he was seven: "Teg had been only seven at the time, but the events lay inedibly in memory." 14933 + 7 = 14940. His brother Sabine had been four. "Even Sabine, who succumbed many years later to a poisoner on Romo, listened with as much of his four-year-old awareness as he could." 14940 - 4 = 14936.
  94. Heretics of Dune, page 42. "Shortly before his thirteenth birthday, Miles Teg was sent away to advanced schooling at the Bene Gesserit stronghold on Lampadas, where his mother’s assessment of him was confirmed." 14933 + 13 = 14946.
  95. Heretics of Dune, page 413
  96. Heretics of Dune, pages 59. "A precocious child of eleven standard years, slender and dark-skinned with sun-streaked brown hair, she could visualise clearly what the priests saw through their spying lenses." 15229 - 11 = 15218.
  97. Chapterhouse: Dune, pages 14-15
  98. Heretics of Dune, page 15. "And fifteen hundred years since the Tyrant's death, the Sisterhood remained powerless to unlock the central knot of that fearsome accomplishment." 13,728 + 1,500 = 15,228. Around a year seems to pass from this point until the attack on the Keep. 15,228 + 1 = 15,229.
  99. Chapterhouse Dune, p. 80. "More than eight Standard Years."
  100. Chapterhouse: Dune, page 127. "Our ghola teg is ten years old." 15,230 + 10 = 15,240.
