The First and Second Children Are Approximately 25 Months Apart Based on Their Birth Months
What is the age gap between Lee Yoo-young's first and second children? Born in August 2024 and September 2026, they are two years apart.# What is the age gap between Lee Yoo-young's first and second children? Born in August 2024 and September 2026, they are two years apart
Lee Yoo-young's first daughter was reportedly born in August 2024, while her second daughter was born in September 2026. Based on their birth months, the gap between the two children is approximately 2 year and 1 month, or about 25 months. It is therefore natural to describe the sisters as being two years apart, rather than as children born in consecutive calendar years.
The First and Second Children Are Approximately 25 Months Apart Based on Their Birth Months
Lee Yoo-young gave birth to her first daughter in August 2024. Her agency announced the birth of her second daughter in September 2026 and stated that both mother and baby were healthy.
Based solely on the publicly reported birth months, the calculation is as follows.
First child: Born in August 2024
Second child: Born in September 2026
Difference between birth years: 2 year
Gap between birth months: Approximately 25 months
Because their exact birth dates have not been disclosed, it is not possible to determine their precise age difference down to the day. However, based on the reported months, the gap can be described as approximately 2 year and 1 month.
How Is a 'Two-Year Age Gap' Calculated?
The Korean term 'teoul' refers to the age difference between an older child and the next child, or the interval between one birth and the next. The National Institute of Korean Language also explains the term as describing the age difference between siblings.
Therefore, if the first daughter was born in August 2024 and the second in September 2026, the sisters can commonly be described as having a two-year age gap.
In this context, a 'two-year age gap' refers more to the approximately 2 year separating their births than to how old the children are at present.
Does That Mean They Were Not Born in Consecutive Years?
In Korean, the term 'yeonnyeonsaeng' is generally used to describe siblings born in consecutive calendar years. For example, if the first child was born in 2024 and the second in 2025, they would be described using this term.
Lee Yoo-young's two daughters were born in 2024 and 2026, with 2025 falling between their birth years. Therefore, under the commonly used definition, they would not be considered siblings born in consecutive years.
The National Institute of Korean Language also recognizes 'yeonnyeonsaeng' as an officially used spelling, while 'yeonnyeon' conveys the meaning of successive years.
Why Are Both '2 Year Apart' and '25 Months Apart' Used?
When discussing the age difference between siblings, people sometimes compare only their birth years, while others calculate the interval using their actual birth months.
Comparing August 2024 and September 2026 by birth year alone gives a difference of 2 year. However, counting the birth months on a calendar gives approximately 25 months, equivalent to about 2 year and 1 month.
That is why the following descriptions of the same two children are not contradictory.
| Calculation Method | Result |
|---|---|
| Based on birth years | 2 year apart |
| Based on birth months | Approximately 2 year and 1 month |
| Expressed in months | Approximately 25 months |
| Common everyday description | Two-year age gap |
If their exact dates of birth become public, the calculated difference in months and days may change.
It Does Not Mean the First Child Is Three Years Old and the Second Is One
A 'two-year age gap' and the children's current ages in completed years are separate concepts.
For example, as of September 2026, the first child would be around 2 years old in completed years, depending on her birthday, while the newborn second child would be 0 years old. However, even as time passes, the interval between their births will remain approximately 25 months.
Therefore, when determining the age gap between siblings, it is more accurate to consider how far apart the children's actual birth dates are rather than asking how old they are now.
How to Understand the Age Difference Between Lee Yoo-young's Two Daughters
In summary, Lee Yoo-young's first daughter was reportedly born in August 2024, while her second daughter was born in September 2026. Based on their publicly reported birth months, the gap is approximately 25 months, meaning the sisters can be described as having a two-year age gap.
Because their birth years are 2024 and 2026, with a calendar year in between, they are distinct from siblings commonly described in Korean as being born in consecutive years. Since their exact birth dates have not been disclosed, it is appropriate to avoid calculating the difference down to individual days, such as '2 year, 1 month, and a certain number of days.'
