In Japan they have two types of dates, which map to “Use by” and “Best before”, but they don’t use them interchangeably or some vague middle-of-the-road term like “expiry date”. One is operative, the other is a recommendation.

消費期限 (shouhi-kigen) literally means “consumption time limit” and 賞味期限 (shoumi-kigen) literally means “guarantee of taste time limit”.
