In Korea, people often use honorifics and appellations such as eonni (older sister) and oppa (older brother) when speaking with someone else.
This is because Koreans generally follow the Confucian tradition of speaking differently with someone who is older versus someone who is younger. This is why Koreans will often ask others their age or the year they were born at the start of a conversation.
Korea's millennial generation is less likely to ask about age when first meeting someone, but it’s not surprising for Koreans to reveal the year they were born to each other.
