JAPANESE_ERAS定数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
The five modern eras, oldest first: 明治, 大正, 昭和, 平成 and 令和.
明治 is dated from 23 October 1868, when the name was proclaimed; its years are counted as if it began with 1868, so 明治1 is 1868 and 明治45 is 1912. Each later era begins the day the emperor before it died, which is also the day the year number starts again from 元年.
