About Months to Years Calculator

The conversion is a single division by 12. The whole-unit and remainder lines are shown because most practical uses — durations, billing increments, schedules — need the integer part and what is left over separately. Mixing time units is a classic source of off-by-a-factor bugs in timesheets, cron schedules and SLA calculations.
