Dahye is from the Korean da (다 — big, much) + hye (혜 — grace, wisdom). Dahye Han (acting career) — appears in major Korean dramas including supporting roles in Korean TV productions; transitioned to acting alongside her K-pop career. Dahye in modern Korean naming — has gained popularity following Dreamcatcher's international success. Princess Dahye — modern Korean heritage naming.
Dahye does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Dahye reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
