start, end, interval, intervalNumber: The first and last calendar years, a readable year range and a separate reign number. A number of 2 means a restored reign.

status, tier: The kind of reign and how much of its dates is confirmed. The code year-only means full dates are not confirmed; ongoing means the reign is still continuing.

yearSpan, yearEligible: The end year minus the start year, and whether the record is included in the approximate-years summary. This length can be a year out because it ignores months and days. true means included; false means omitted.

exactStart, exactEnd, calendar, endCalendar, yearStyle: Full dates in year-month-day form, their calendars and when a calendar year begins. UNKNOWN means the full date has not been confirmed. A blank end date means an ongoing reign.

daySpan, inclusiveDays, dayEligible: Elapsed days, days counting both the first and last date, and whether the reign is included in day-length statistics. true means included; false means omitted. Blank numeric cells mean no confirmed value, rather than zero.

agreement, retrieved, startNote, endNote, exactNote: AGREE means the two compared chronologies give the same chosen dates; DISAGREE means they differ. Other sources can give additional dates. retrieved is the date the sources were consulted. The note fields explain the dates used.

primary, secondary, secondaryObservedDates: Links to the two compared sources and the dates given by the second source. These column names identify the sources; they do not mean every source agrees.

exactSources, dateEvidence, regnalStatus: Source links, supporting passages and whether numbered royal years are supported. Source entries are separated by | and their named fields by semicolons. bodyHash is a fingerprint of the saved source text, allowing a later check that it has not changed.

supportingFact, observedSource, observedSourceHash, evidenceStatus: Extra columns in the download with sources: the date explanation, links, saved-text fingerprints and whether the evidence confirms both dates needed for a length calculation.

Reading the older notes: The downloadable files are unchanged, so their older notes keep their original wording. The records were last checked on 28 September 2026; that is not the end of a numbered year. The downloadable guide gives a plain explanation for every reign; each Details panel gives the dates and sources.

Plain explanations of the unchanged download notes

William I: The Royal Family gives his death as 9 September 1087. Wikipedia starts the reign at his coronation on 25 December 1066. The accession date is not confirmed here, so this reign is not ranked by days. Westminster Abbey also mentions 8 or 9 September for his death.

William II: Westminster Abbey gives his death as 2 August 1100 and his coronation as 26 September 1087. Wikipedia uses that coronation date to start the reign. A confirmed accession date is needed before a length in days can be given.

Henry I: Westminster Abbey gives his death as 1 December 1135 and his coronation as 5 August 1100. Wikipedia starts the reign at the coronation. The accession date is not confirmed here.

Stephen: Westminster Abbey gives his death as 25 October 1154. Wikipedia starts the reign on 22 December 1135. The cited evidence does not confirm an accession date, so the page gives an approximate length in years.

Henry II: Westminster Abbey gives his death as 6 July 1189 and his coronation as 19 December 1154. Wikipedia uses the coronation to start the reign. The page leaves the accession date unconfirmed.

Richard I: Westminster Abbey gives his death as 6 April 1199 and his coronation as 3 September 1189. Wikipedia uses the coronation to start the reign. The page leaves the accession date unconfirmed.

John: Hereford Cathedral gives his death as 19 October 1216. Wikipedia starts the reign on 27 May 1199, but the cited evidence does not confirm that as the accession date. His numbered royal years follow Ascension Day and are explained separately.

Henry III: English Heritage says Henry III succeeded on 19 October 1216 and died on 16 November 1272; these are the dates used here. Wikipedia starts the reign at his first coronation on 28 October. Becoming king and being crowned were separate events.

Edward I: History of Parliament dates his succession to 16 November 1272, when Henry III died. The Royal Family also describes this succession. Wikipedia starts the reign on 20 November, the date of formal recognition and his father’s funeral. This page uses 16 November.

Edward II: Britannica’s 1911 biography describes Edward II becoming king when Edward I died on 7 July 1307. Wikipedia starts the reign on 8 July. The page uses 7 July and ends the reign at his renunciation on 20 January 1327, rather than his death in September.

Edward III: English Heritage gives 24 January 1327 as his succession and declaration as ruler, and 21 June 1377 as his death; these are the dates used here. Wikipedia starts the reign on 25 January. Britannica’s 1911 account gives parliamentary recognition on 13 January. His coronation on 1 February was a separate event.

Richard II: The Law Foundation’s reign table starts his reign on 22 June 1377. This page ends it at his deposition on 30 September 1399, following Britannica’s 1911 account. Wikipedia instead ends it at his abdication on 29 September.

Henry IV: The Law Foundation starts his reign on 30 September 1399; Westminster Abbey gives his death as 20 March 1413. Wikipedia gives the same dates. His coronation on 13 October 1399 was a separate event.

Henry V: Fine Roll 1 Henry V dates new writs to 21 March 1413, the opening day of his reign. The Law Foundation and Wikipedia give the same start date. Westminster Abbey and Wikipedia give his death as 31 August 1422. The Royal Family’s list confirms the years, rather than both full dates.

Henry VI: History of Parliament starts his first reign on 31 August 1422. Wikipedia and Westminster Abbey describe his kingship beginning on 1 September. The page uses 31 August and ends this first reign on 4 March 1461; his later restored reign is listed separately.

Henry VI (restored reign): Cheney’s regnal-year table, scanned by the Folger Shakespeare Library, gives 3 October 1470 to 11 April 1471 for Henry VI’s restored reign. Wikipedia’s regnal-year table starts his formal restoration on 9 October. The page shows Cheney’s dates for document dating, but does not use them to rank this reign by days.

Edward IV: History of Parliament and Wikipedia give 4 March 1461 to 3 October 1470. These dates describe Edward IV’s first reign; his restored reign is listed separately.

Edward IV (restored reign): History of Parliament and Wikipedia give 11 April 1471 to 9 April 1483 for his restored reign. The page keeps this separate from his first reign.

Edward V: Westminster Abbey and Wikipedia give 9 April to 25 June 1483. This reign is ranked by days. It is omitted only from the approximate-years summary because it began and ended in the same calendar year.

Richard III: History of Parliament starts his reign on 26 June 1483 and ends it on 22 August 1485; these are the dates used here. Westminster Abbey describes his proclamation on 25 June. His coronation on 6 July was a separate event.

Henry VII: History of Parliament and Wikipedia give 22 August 1485 to 21 April 1509 for Henry VII. The page uses these dates to calculate elapsed days.

Henry VIII: History of Parliament starts his reign on 21 April 1509, when he became king. Wikipedia and the University of Victoria regnal-year table use 22 April. The page uses 21 April for reign length and 22 April for numbered years. His coronation on 24 June was a separate event.

Edward VI: History of Parliament and Wikipedia give 28 January 1547 to 6 July 1553 for Edward VI. The page uses these dates to calculate elapsed days.

Mary I: This page starts Mary’s reign at her proclamation on 19 July 1553, the date used by Wikipedia’s reign list and her first numbered year in the University of Victoria table. History of Parliament starts it on 6 July, when she inherited the right to the throne. Both end it on 17 November 1558. Later numbered years begin on 6 July. Philip’s numbered years begin on 25 July.

Elizabeth I: History of Parliament and Wikipedia give 17 November 1558 to 24 March 1603 for Elizabeth I. The page uses these dates to calculate elapsed days.

James I: History of Parliament and Wikipedia give 24 March 1603 to 27 March 1625 for James I. The page uses these dates to calculate elapsed days.

Charles I: History of Parliament and Wikipedia give 27 March 1625 to 30 January 1649 for Charles I. The page uses these dates to calculate elapsed days.

Charles II: This page starts Charles II’s restored reign at his arrival in London on 29 May 1660, following History of Parliament and Wikipedia, and ends it at his death on 6 February 1685. History of Parliament says the Convention Parliament proclaimed him king on 8 May; Parliament’s overview dates formal restoration and proclamation to 14 May. These accounts describe different events. His numbered years run from 30 January 1649, so the restored reign begins partway through year 12. His coronation on 23 April 1661 was separate.

James II: History of Parliament and Wikipedia end the reign at James II’s final departure on 23 December 1688. The regnal-year table instead ends his numbered years on 11 December, the date used for his abdication. This page uses 23 December for reign length and 11 December for document dating.

William III: William III and Mary II began their joint English reign on 13 February 1689. William continued alone after Mary died on 28 December 1694, until his death on 8 March 1702. History of Parliament records the joint and sole periods separately; this page combines them as one William III reign and lists Mary separately. Cheney’s table at the Folger Shakespeare Library changes William’s numbered-year anniversary from 13 February to 28 December; the Colonial Society table keeps 13 February.

Mary II: History of Parliament and Wikipedia give 13 February 1689 to 28 December 1694. Mary ruled jointly with William III until her death; William’s reign continued to 1702. Cheney’s table at the Folger Shakespeare Library ends their joint numbering on 27 December, one day before her death.

Anne: Anne’s reign continued from 8 March 1702 to 1 August 1714. History of Parliament and Wikipedia describe the English period before the union of 1 May 1707 and the British period after it. The page combines those periods into one reign; the union did not restart her numbered years.

George I: History of Parliament gives 1 August 1714 to 11 June 1727 in the Julian calendar. Westminster Abbey gives his death in Germany as 22 June 1727 in the Gregorian calendar. Those two death dates describe the same day.

George II: History of Parliament and Wikipedia give 11 June 1727 to 25 October 1760. The start is Julian and the end Gregorian, because England changed calendars in 1752. His numbered years across that change are explained in the converter rules.

George III: History of Parliament records George III’s British reign before the union of 1801 and his United Kingdom reign after it. Together with Wikipedia, these give 25 October 1760 to 29 January 1820. The page combines the periods as one continuous reign.

George IV: History of Parliament and Wikipedia give 29 January 1820 to 26 June 1830 for George IV. The page uses these dates to calculate elapsed days.

William IV: History of Parliament and Wikipedia give 26 June 1830 to 20 June 1837 for William IV. The page uses these dates to calculate elapsed days.

Victoria: History of Parliament and Wikipedia give 20 June 1837 to 22 January 1901 for Victoria. The page uses these dates to calculate elapsed days.

Edward VII: History of Parliament and Wikipedia give 22 January 1901 to 6 May 1910 for Edward VII. The page uses these dates to calculate elapsed days.

George V: History of Parliament and Wikipedia give 6 May 1910 to 20 January 1936 for George V. The page uses these dates to calculate elapsed days.

Edward VIII: History of Parliament and Wikipedia give 20 January to 11 December 1936. Subtracting those dates gives 326 days; counting both dates gives 327. The Royal Family biography reports 325 days. Edward signed his abdication on 10 December, but it took legal effect on 11 December. This reign is ranked by days and omitted only from the approximate-years summary.

George VI: History of Parliament and Wikipedia give 11 December 1936 to 6 February 1952 for George VI. The page uses these dates to calculate elapsed days.

Elizabeth II: History of Parliament and Wikipedia give 6 February 1952 to 8 September 2022 for Elizabeth II. The page uses these dates to calculate elapsed days.

Charles III: The Royal Family says Charles III became king on 8 September 2022. He was still reigning when these records were checked on 28 September 2026, so they give no completed reign length. That check date is not the end of his reign. His proclamation on 10 September 2022 and coronation in 2023 were separate events.
