According to the light novel, Haruhi Suzumiya (涼宮ハルヒ Suzumiya Haruhi) entered North High in April of 2003. Other sources report that her birthday was October 8th, so she presumably was 16 in 2002, and so was born in 1986. That makes her 30 years old today. She’s now an adult, middle-aged, having graduated college nine years ago, probably married Kyon, and now has a couple of kids, named Natsu and Aki. How fleeting are the days of youth.
Happy Birthday Haruhi
