This page is a Timeline of the events that occur before, during and after the opening of the Time Tombs on the planet Hyperion. Most dates are listed in the Common Era, known in the time of the Hegemony as the "old calendar" or "old reckoning"[1]. Dates in the Common Era numbering system use the following designations:

  • BCE - Before the Common Era
  • CE - Common Era

A new calendar was adopted following the establishment of the Hegemony of Man. Dates in the Hegemony Standard calendar are provided, when known:

  • PC - Present Calendar - used for dates after the founding of the Hegemony of Man[2]

After the fall of the Hegemony, dates were typically calculated in terms of "years after the fall"

  • AF - Years After the Fall - used for dates after the fall of the Hegemony of Man

Additionally, individual planets almost always have a local calendar, typically based on the local solar year. A relevant local calendar is that used on the planet Hyperion:

  • ADC - After Dropship Crash - a designation used for local dates on the planet Hyperion.

Note: It is assumed in all the calculations below that a "standard" year is an Old Earth year, consisting of 365.2425 days. Dates in local calendars will obviously use a different year length, which may add uncertainty to calculations involving local dates or based on statements where the length/type of year is unspecified.

Circa 500 BCE

Circa 33 CE

  • Jesus of Nazareth was the first Human to understand the Void that Binds. While alone in the wilderness, he travelled to the future - the time following his crucifiction - and worked his miracles on Earth. This is why he was believed to have risen from the dead. This is explained by Aenea in The Rise of Endymion

2038 CE

  • "Nuclear Jihad" wipes out the shortly-lived nation of Palestine on Old Earth.[4]

2143 CE = 0 PC

  • Year zero in the Hegemony Standard Calendar.[5] Presumably, the date of the founding of the Hegemony.

2200s CE

  • 2238 - The Big Mistake - a team in Kiev creates a black hole that begins to devour Old Earth from the inside out for the next 100 years.[6] This year is 526 years prior to the Final Shrike Pilgrimage and 95 years after the founding of the Hegemony.
  • Some time later - The Ousters leave Old Earth System 450 years prior to their encounter with the Consul[7]; this is after the Big Mistake, since they have data regarding the origin of the Big Mistake at the time. It is also prior to Martin Silenus's birth, since he references the Ouster migration in his early childhood.[8]
  • 2282 - The Hegira begins. Humanity leaves Old Earth for the stars.[9] This year is 44 years after the Big Mistake.

2300s CE

  • 2318 - Martin Silenus is born on Old Earth.[10]
  • 2338 - The Death of Old Earth. Martin Silenus departs Old Earth for Heaven's Gate.[10]
  • In this intervening period while Martin "slept", the Hegemony was formalized and the WorldWeb spun into something close to its final shape. The All Thing took its place, the TechnoCore seceded, and the Ousters retreated to darkness. All had been in progress prior to Martin's departure for Heaven's Gate. [11]

2400s CE

  • A. Bettik is bio-manufactured in the twenty-fifth century AD, in the year 26 ADC on the local Hyperion calendar.[12]

2500s CE

2732 CE = 589 PC = 426 ADC

  • Day 1 of Father Paul Duré's exile on the planet Hyperion = 17 Thomasmonth 2732 CE = October 12, 589 PC = 23 Lycius 426 ADC.[23]

2739 CE

2761 CE

2764 CE

2852 CE = 2852 AD

2861 AD

2978 AD

  • The archbishop of Tau Ceti Center, His Excellency Klaus Cardinal Kronenberg is excommunicated from the Catholic Church.[30] This is year 126 After the Fall.

3099 AD

  • Raul Endymion is born on the planet Hyperion.[31] This is year 693 ADC on the local Hyperion calendar and year 247 After the Fall.

3126 AD

3131 AD


  1. 1.0 1.1 Hyperion, 1995. 264 - Melio uses the term "old reckoning" in his recording to Rachel after she contracts Merlin's sickness. The term "old calendar" is used elsewhere in Hyperion. Need a reference.
  2. Hyperion, 1995. 31 - The PC designation was used by Father Paul Dure when computing the date of the beginning of his exile. The assumption that PC stands for Present Calendar is conjecture.
  3. Date from [[1]] - This event is included in this list as a basis for the comment by Martin Silenus that democracies had been around for approximately three thousand years prior to the Hegira.
  4. Hyperion, 1995. 133.
  5. Assuming the Hegemony Standard calendar starts at the founding of the Hegemony of Man, year zero is 589 years prior to 2732 CE. (Hyperion, 1995. 31.) We do know that the Hegemony was founded "decades" prior to the Big Mistake, since the Consul states the Big Mistake had been planned by the Technocore and "the fledgling government of the Hegemony". (Hyperion, 1995. 468.)
  6. 6.0 6.1 The Big Mistake occurs in a year ending in '38 (Hyperion, 1995. 468). The year is 2238 based on the following calculation: Old Earth dies 100 years later (Hyperion, 1995. 183). Martin arrives at Heaven's Gate 167 years after that (Hyperion, 1995. 187). He remains on Heaven's Gate for 4 years (1500 days - Hyperion, 1995. 189) then spends 3 years writing Dying Earth II and 6 more writing up to Dying Earth IX (Hyperion, 1995. 206). Martin moves to Asquith and knows King Billy for "several" (assume 2) years prior to departing for Hyperion (Hyperion, 1995. 213). Arrival to Hyperion is four years later - one year between Asquith and the Web (Hyperion, 1995. 212) and three more to Hyperion (Hyperion, 1995. 4). This puts the date of arrival to Hyperion at 2338+100+167+4+3+6+2+4=2524, which is 240 years prior to the Final Shrike Pilgrimage in 2764. We know that Sad King Billy's colonization of Hyperion occurs between 200 (Hyperion, 1995. 179) and 250 (Hyperion, 1995. 233) years prior to 2764. Q.E.D.
  7. Hyperion, 1995. 468.
  8. Hyperion, 1995. 182.
  9. Melio states that 2739 CE is 457 years after the Hegira (Hyperion, 1995. 264.) Martin states that the Old Earth families began to sponsor migrations "After three thousand years of dabbling with democracy." (Hyperion, 1995. 182.) 2282 is 2782 years after the first democracies circa 500 BCE. Q.E.D.
  10. 10.0 10.1 Old Earth dies 100 years after the Big Mistake. (Hyperion, 1995. 183.) Martin Silenus is 20 years old at the time. (Hyperion, 1995. 186.)
  11. Hyperion, 1995. 189.
  12. Endymion, 1995, 57.
  13. 167 years after departing. Hyperion, 1995. 187.
  14. 1500 standard days on Heaven's Gate. Hyperion, 1995. 189.
  15. Hyperion, 1995. 206.
  16. Hyperion, 1995. 210.
  17. Martin knows Sad King Billy for "several" years prior to departing Asquith. Hyperion, 1995. 213.
  18. After nine years of decadence. Hyperion, 1995. 217.
  19. Hyperion, 1995. 224.
  20. Hyperion, 1995. 225.
  21. 12 years after the first appearance of the Shrike. Hyperion, 1995. 226.
  22. Hyperion, 1995. 233.
  23. Hyperion, 1995. 31. This should be approximately 400 years after the death of Old Earth (Hyperion, 1995. 26) With the Death of Old Earth in 2338, this date is 394 years later.
  24. Six months prior to Melio's recording. Hyperion, 1995. 264.
  25. Hyperion, 1995. 265.
  26. Three years prior to the Final Shrike Pilgrimage, due to the three year time debt between Parvati and Hyperion. (Hyperion, 1995. 4.)
  27. Rachel was 25 years old when she contracted Merlin's sickness in 2739. (Hyperion, 1995. 265.) She is five days old as the pilgrims descend into the valley, which is therefore 25 years after 2739. (The Fall of Hyperion, 1995. 16.)
  28. The year of the Fall is computed from Raul's statement that he was born in the year 3099 AD, which was 247 years After the Fall - Endymion, 1995, 5. It is consistent with Father Dure's statement that the year 3131 is 279 years After the Fall - The Rise of Endymion, 1997, 19.
  29. 270 years prior to the year 3131. The Rise of Endymion, 1997, 19.
  30. Endymion, 1995, 304.
  31. Endymion, Chapter 2.
  32. Endymion, 1995, Back cover description: "It is 274 years after the Fall...".
  33. The Rise of Endymion, 1997, 19.
