Origin
Meaning and history of Dayjon
The name Dayjon is a relatively modern variant of the name Daejon, which has its origins in the Korean language. The prefix "Dae" is derived from the Korean word for "great" or "large," while the suffix "jon" is a common ending for Korean male names. This suggests that the name Dayjon may have originated as a name bestowed upon a child with the hope that they would grow to become a great or accomplished individual.
Although the name Dayjon is not found in ancient texts or historical records, its root name, Daejon, has been in use in Korea for centuries. One of the earliest recorded instances of the name Daejon can be found in the annals of the Goryeo Dynasty, which ruled Korea from 918 to 1392 CE. During this period, a prominent scholar and government official named Daejon Kim (1134-1199) served as a chief minister under King Myeongjong.
In more recent times, several notable individuals have borne the name Dayjon or its variants.

Another individual of note is Dayjon Park (born 1976), a South Korean professional golfer who has won multiple tournaments on the Asian Tour and Japan Golf Tour. He has represented South Korea in various international competitions, including the World Cup of Golf.

FAQ
Dayjon: questions and answers
How many people in the U.S. are named Dayjon?
Name Census puts the figure at roughly 47 living Americans. We arrive at this by taking every SSA birth registration for Dayjon 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 7,292,645 US residents.
Is Dayjon a common name?
We classify Dayjon as "Very Rare". It ranks above 53.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 48 babies have been registered with this name.
When was Dayjon most popular?
The single biggest year for Dayjon was 1999, when 7 babies received the name. The fact that the average living Dayjon is about 20 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 Dayjon in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Dayjon a male name?
Yes, 100.0% of people registered as Dayjon 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 Dayjon still being used today?
Yes. The SSA still recorded Dayjon 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 Dayjon 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.
