Origin
Meaning and history of Aldayr
The name Aldayr has its roots in the ancient Arabic language and culture. The earliest known origins of this name can be traced back to the 7th century AD, during the time of the Islamic Golden Age. It is believed to be derived from the Arabic word "al-dayr," which translates to "the monastery" or "the convent."
One of the earliest recorded historical references to the name Aldayr can be found in the writings of the renowned Arab scholar and historian, Ibn Khaldun, who lived from 1332 to 1406. In his seminal work, "The Muqaddimah," he mentions a figure named Aldayr ibn al-Hasan, who was a prominent leader and military commander during the Abbasid Caliphate in the 9th century.
The first significant individual to bear the name Aldayr was Aldayr ibn Abi al-Rahal, a celebrated Arab poet who lived in the 10th century. His poetry was widely acclaimed for its depth, elegance, and mastery of the Arabic language. Unfortunately, little is known about his life beyond his literary works.
Another notable figure who carried the name Aldayr was Aldayr al-Andalusi, a renowned Andalusian scholar and philosopher who lived from 1063 to 1144. He was born in Cordoba, Spain, during the golden age of Islamic civilization in the Iberian Peninsula. Aldayr al-Andalusi made significant contributions to the fields of mathematics, astronomy, and philosophy, and his writings were widely studied throughout the Islamic world.
In the 13th century, Aldayr ibn Abi al-Fath al-Baghdadi was a prominent Islamic jurist and legal scholar from Baghdad. He was known for his expertise in Islamic jurisprudence and his influential works on the interpretation of Sharia law.
Another notable figure bearing the name Aldayr was Aldayr al-Dimashqi, a Syrian historian and writer who lived from 1501 to 1584. He is best known for his comprehensive chronicle of the history of Damascus, titled "Nukhbat al-Dahr fi 'Aja'ib al-Barr wa'l-Bahr" (The Cream of the Age Concerning the Marvels of the Land and Sea).
While the name Aldayr has its roots in the Arabic language and culture, it has also been adopted and adapted in various other regions and contexts throughout history. However, the historical records and references mentioned above provide a glimpse into the rich heritage and significance of this distinctive name.

FAQ
Aldayr: questions and answers
How many people in the U.S. are named Aldayr?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Aldayr going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 68,550,868 US residents.
Is Aldayr a common name?
We classify Aldayr as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Aldayr most popular?
The single biggest year for Aldayr was 1999, when 5 babies received the name. The fact that the average living Aldayr is about 27 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Aldayr in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Aldayr a male name?
Yes, 100.0% of people registered as Aldayr in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Aldayr still being used today?
Yes. The SSA still recorded Aldayr in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Aldayr can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
