Japanese students are separated into years on April 1st, the same day a new school year starts. The oldest possible person in a grade would be born on April 1st, and the youngest would be born on March 31st of the next calender year. If Mio had been born on January 15th, 1991, she would be a year above everyone else. This also means that every single student is 15 on their first day of high school.
