Does anyone know how old any of the guys are?

Ruki was born 1st Feb, 1982, making him 27. Kai was born 28th Oct, 1981, so right now he's 27 but he'll be 28 in October. Reita was born 27th May, 1981, so he's coming up for 28 too. Uruha was born 9th June, 1981, so same for him. Aoi was born 20th January, 1979, making him 30.
If I'm wrong about any of it, blame the Internet :P
