Under CCP 12, courts must use the “anniversary method” of computing statutes of limitation periods, excluding the first day of the period and including the last (unless it is a holiday or weekend).  Thus, for a personal injury suit by a minor, the limitations period begins on the minor’s 18th birthday.  That day is excluded, and the 2-year personal injury limitations period expires on the minor’s 20th birthday, including that date unless it is a Saturday, Sunday or holiday, in which case the limitations period ends on the next regular day.  Ganahl v. Soher (1884) 2 Cal.Unrep. 415, which applied the calendar method without mentioning CCP 12, never had precedential force since the court granted review in bank, thus automatically vacating the cited panel decision.
