Initial version
Zois progress through 9 life stages. Rather than aging gradually, they transition instantly from one stage to the next, with their appearance changing immediately. One in-game Zoi Day lasts 96 real-world minutes by default, and players can adjust this in settings. There is no way to completely stop aging or prevent death from old age.
Newborn -- 1 day. Only occurs through birth. Not selectable in Create-a-Zoi.
Toddler -- 2 days (cumulative: 3). Follows Newborn. Not selectable.
Child -- 7 days (cumulative: 10). Attends elementary school. Selectable at creation.
Adolescent -- 5 days (cumulative: 15). Attends middle school. Not selectable.
Teenager -- 5 days (cumulative: 20). Attends high school. Selectable. Can drive cars.
Young Adult -- 10 days (cumulative: 30). Can attend university, become an idol trainee, or work. Selectable.
Adult -- 20 days (cumulative: 50). Full career access. Selectable.
Middle-Aged -- 15 days (cumulative: 65). Full career access. Selectable.
Senior -- Variable. Zois pass away from old age during this stage, roughly 17 in-game days after entering it. Selectable.
Newborn, Toddler, and Adolescent cannot be selected when creating a Zoi -- they can only be reached through gameplay (birth or aging). The selectable stages are Child, Teenager, Young Adult, Adult, Middle-Aged, and Senior.
