名前	型	説明
`kanji`	`string`	The name in kanji, which is how a date is written.
`romaji`	`string`	The Latin name, capitalised as English writes it.
`reading`	`string`	The reading in hiragana, for anyone meeting the kanji for the first time.
`startYear`	`number`	The Western year the era's first year falls in.
`lastYear`	`number \| null`	The highest year the era reached, or null while it is still running. 昭和 ran to 64 and 平成 to 31, so 昭和65 is not a date and answering with 1990 would be a wrong answer rather than a missing one.
`startDate`	`string`	The era's first day, as `YYYY-MM-DD`: the day the emperor's reign, or for 明治 the name itself, began.
`endDate`	`string \| null`	The era's last day, as `YYYY-MM-DD`: the day before the next era began. Null while it is still running.
`spellings`	`readonly string[]`	Every spelling the name is written with in Latin letters, in lower case. The long vowels are the reason there is a list rather than one string: 昭和 is Showa, Shouwa and Shōwa depending on whose romanization somebody learned, and all three are the same era.
