I've been a bit of a gossip-hound for K-ent news, so I keep tabs on this stuff: Park Bo-young's husband is actor Choi Tae-joon, who was born in 1991. That means, by simple Western/international age math, you take 2025 minus 1991 and get 34 — but only if his birthday already happened this year. If his birthday falls later in the year (after August 30, 2025), he'd still be 33 until that date.
If you factor in the traditional Korean age system (the older way where you're one at birth and everyone gets a year older on New Year's), he'd commonly be referred to as 35 in Korea during 2025. I always get a little tickled by how many fans mix the two systems when celebrating birthdays on social media, so you’ll sometimes see different numbers floating around depending on where a post comes from.
So short practical take: Choi Tae-joon — born 1991 — is either 33 or 34 by international age as of today (2025-08-30), and typically called 35 by traditional Korean age. If you want the exact Western age right now, just check his birthdate month and day and compare to today; I usually look at a reliable profile like a news agency piece or his agency’s official profile to be sure.
