What are the birthdates of Archie and Lilibet Mountbatten-Windsor?
1. Birthdates and places: the simple facts
Archie’s birthdate is consistently reported as 6 May 2019 and multiple reputable profiles list his time of birth as about 05:26 at Portland Hospital in Westminster, London [1] [2]. Lilibet’s birthdate is consistently reported as 4 June 2021, with sources giving her time as 11:40 a.m. Pacific Daylight Time and naming Santa Barbara Cottage Hospital as the place of birth [3] [4].
2. Primary public confirmations: official notices and certificates
Archie’s birth was publicly confirmed by official announcements and his birth certificate was later released, which stated the 6 May 2019 birth at Portland Hospital [5]. Lilibet’s arrival was announced by her parents and recorded by mainstream reference outlets that cite the hospital and exact time on 4 June 2021 [3] [6]. These announcements and civil documents are the core contemporaneous public records reporters rely on [5] [3].
3. Timing, title context and how reporting framed the events
Contemporaneous royal communications stressed parental choices about titles and privacy: at Archie's birth the couple opted against an immediate coronation‑style photocall and later chose not to use a title for him at first, details that accompanied the birth reporting [1] [7]. When Lilibet was born in the U.S., reporting similarly combined the birth facts with context about nationality and later decisions on titles following changes in the monarchy [3] [6].
4. Time zones and the importance of notation
Lilibet’s time is reported in local U.S. Pacific time (11:40 a.m. PDT) and converted to UTC in some records (18:40 UTC), which is relevant when cross‑checking sources internationally [3] [4]. Archie’s time is given in UK local time (05:26), and some outlets repeat that exact minute when citing the birth certificate [2] [5]. When quoting birth times across outlets, note whether the source lists local time or a UTC conversion to avoid apparent contradictions [3] [2].
5. Consistency across sources and minor variations
Major biographical and news outlets cited here — including biography pages, the Royal Family website, and longform profiles — agree on the dates and hospitals for both children [1] [8] [2] [3] [6]. Some fan wikis and aggregator pages repeat the same facts; minor differences in phrasing (e.g., “Master Archie” or “Prince Archie of Sussex” in later updates) reflect changes in status and editorial choices rather than disputes about birthdates [9] [10] [11].
6. What the current reporting does not address
Available sources do not mention any credible dispute over the birthdates or places of birth for either child; they do not provide contradictory official records. If you’re seeking the original, primary civil documents beyond the cited summaries (e.g., scanned certificates), available sources here do not include direct scans or PDFs of those documents for independent verification [5].
7. Why these basic facts became politically and culturally salient
Reporters framed Archie’s 2019 birth as notable because of Meghan’s American citizenship and mixed‑race heritage and because the couple later stepped back from senior royal duties — context repeatedly included in birth coverage [8] [7]. Lilibet’s U.S. birth amplified conversations about nationality, titles and the family’s residency in California; coverage often paired the birth facts with commentary about naming choices that honored Queen Elizabeth II and Princess Diana [3] [6].
8. How to cite these dates going forward
For straightforward biographical references: cite 6 May 2019 and 4 June 2021, and, if needed, add times and locations (Archie: 05:26, Portland Hospital, London; Lilibet: 11:40 a.m. PDT, Santa Barbara Cottage Hospital) as sourced here [2] [3]. If you need scanned primary documents or further legal proof, those are not supplied in the current set of sources and would require direct retrieval from public records or official releases [5].
Summary conclusion: Multiple independent and official‑style sources concur that Archie was born 6 May 2019 in London and Lilibet was born 4 June 2021 in Santa Barbara, CA; reporting supplements these dates with times, places and context about titles and nationality [1] [2] [3] [4].
