Queen Elizabeth II, born Elizabeth Alexandra Mary in London, was the first child of Prince Albert, Duke of York (later King George VI), and his wife, the former Lady Elizabeth Bowes-Lyon. Her birth took place at 2:40 am local time at 17 Bruton Street in Mayfair.

Why 21 April is the authoritative birth date
The date 21 April 1926 is recorded in the Court Circular and corroborated by multiple authoritative biographies issued by the royal household and reputable historians. Contemporary newspaper announcements published on 22 April 1926 confirm the birth. These documents form the evidentiary baseline, making the date a verifiable historical fact rather than a matter of interpretation or convention.
Birthplace and family context
Elizabeth Alexandra Mary entered the world at 17 Bruton Street, a private residence in London’s Mayfair district. Her father, Prince Albert, was the second son of King George V; her mother, Lady Elizabeth Bowes-Lyon, was the daughter of the 14th Earl of Strathmore and Kinghorne. This lineage connected her directly to both royal and aristocratic branches of British society, shaping her early environment and future constitutional role.
Becoming heir presumptive unexpectedly
Elizabeth’s path to the throne changed abruptly on 11 December 1936 when her uncle Edward VIII abdicated. Overnight, she moved from being a royal granddaughter near the periphery of succession to the heir presumptive, second only to her father, now King George VI. This transition was neither planned nor publicized as historic at the time, but it redefined her childhood and prepared her for future sovereign duties.
Public celebration dates differ from the true birth date
In the United Kingdom, the official public observance of the monarch’s birthday is not tied to the calendar date. Instead, it is marked on the second Saturday in June each year through Trooping the Colour. This tradition allows for more reliable outdoor conditions and ceremonial display. Elsewhere, such as in Canada, the official observance falls on a different fixed Monday. These adjusted dates serve practical and climate considerations, while 21 April remains the historically accurate birth date.
Comparison: birth date versus public celebration date
- 21 April 1926: Actual date of birth, documented contemporaneously and used in all formal records.
- Second Saturday in June (UK): Official public celebration, established by military and ceremonial custom.
- Alternative observances: Commonwealth realms may hold separate official days that align with national traditions rather than the private calendar date.
Common questions and clarifications
Because the public celebration occurs months after April, some assume confusion about the real birth date. However, royal registries, baptismal records from May 1926, and consistent citations across decades of official biographies confirm 21 April 1926. Time-zone, calendar reform, or republican sentiment do not alter this factual baseline; they only explain why the anniversary is not always marked publicly on the exact day.
Why precise birth details matter for constitutional history
Queen Elizabeth II’s birth set the conditions for a long and continuous line of succession. Her arrival established a stable point around which modern royal duties, public engagements, and ceremonial protocols could evolve. Accurate records underpin reliable genealogies, legal succession, and transparent public understanding of how constitutional monarchies manage continuity across generations.
