When calculating the insured period, it is to be calculated by the month, and the months from the month in which the day on which the person acquired status as an insured person falls, up to the month preceding the month in which the day on which the person lost that status falls, are to be included in it.
被保険者期間を計算する場合には、月によるものとし、被保険者の資格を取得した日の属する月からその資格を喪失した日の属する月の前月までをこれに算入する。
When an insured person loses status as an insured person in the month in which the day of acquiring that status falls, that month is included in the insured period as one month. However, this does not apply when the person acquires status as an insured person again in that month.
被保険者がその資格を取得した日の属する月にその資格を喪失したときは、その月を一箇月として被保険者期間に算入する。ただし、その月にさらに被保険者の資格を取得したときは、この限りでない。
For a person who, after losing status as an insured person, has again acquired that status, the insured periods before and after are aggregated.
被保険者の資格を喪失した後、さらにその資格を取得した者については、前後の被保険者期間を合算する。
