Cutkillavince sent me this email early this morning

It seems Miss Dica got it wrong
Feb 15th is HMH birthday, There’s message on it on her korean fan cafe
^^

Cutkillavince went on to say that Feb 15th is her birthday in our calendar, but “Feb 15th is Jan 21st in Lunar/Chinese calendar which is used also by Koreans. She was born apparently Feb 15th 1982, and this year 2009, her lunar/chinese BDay is year 2009, month 1, day 21 (2009-01-21).” His findings using a calendar converter found here.

So back in January 21st when we celebrated her 27th birthday…well, it might not be true. In that case, it is Happy Gregorian Birthday to HMH today.
