https://www.tokyo-icc.jp/guide_eng/educ/01.html Going by this again, since Taichi is confirmed 17 (not 16 - 11th grade consists of ages 16~17, meaning Taichi's actually closer to 17), and Koushiro+Mimi are both about a year younger, that'd "likely" place them closer to 16 at start of Tri despite 10th grade/1st year of high school consisting of ages 15~16. Then, by December 2005, they'd be almost a full year older too already by the end...? (The Japanese school year begins in April and ends in March. Digimon as a whole w/each season takes place mainly during the summer/August. December at the end of Tri = only three months before March etc.)
