Changes

The traditional way of expressing the [[age]] of a person in Japan and other east Asian countries, "year-count" (kazoe-doshi 数え年), is different from that used in the west, called "full-year" (man-nenrei 満年齢).  In the latter system, "She was 42-years old" means that at least 42 but less than 43 full years have passed since she was born.  However, in the year-counting system, it could be paraphrased "She is in her 42nd (calendar) year since birth."  When a person is born, he is in his first year of life.  At the next new year, and every new year after that, one year is added to his age, regardless of when in the year he was born.
