周年纪念日怎么算？How are anniversaries counted?
按日历日计算：从纪念日起每过一个完整日历年为一个周年。总天数不含当天；“第 N 天”把纪念日当天算作第 1 天，所以第 100 天 = 纪念日 + 99 天。月份按日历计：若某月没有对应的日子（如 31 日），按该月最后一天算满 1 个月。By the calendar: each full calendar year from the date is one anniversary. Total days excludes the start day; "day N" counts the start day as day 1, so day 100 is the date + 99 days. Months are calendar months: if a month has no matching day (such as the 31st), its last day completes the month.
