20211202 (Palindrome Date)
日本ではもう１２月３日だけれど。。。何処かに忘れないように。記憶に残しておきたくて。やっぱりnoteに書いてしまおうと思います！
夕方ふとBingに出てきたニュースを読んだ。
今日は、西暦で日付（数字）を前から読んでも後ろから読んでも同じ日なんだそうだ。知らなかったなぁ。新英単語もゲット！
２０２１年は、Palindrome Date量産の年！
それも今日だけじゃなくて、２０２１年は”２２”もあるそうだ。（少なくとも４桁の日付）
注：アメリカは月日年の順での表示あり

Thursday marks an eight-digit palindrome, which occurs only 12 times this century. The next one doesn't come until March 2, 2030, spelled out numerically as 03/02/2030.
That's according to Aziz Inan, an electrical engineering professor at the University of Portland who has tracked the dates for years.
He told the Farmer's Almanac that 2021 has 22 palindrome dates of at least four digits, which won't happen again for 90 years, in 2111.
Today's rare palindrome comes toward the beginning of a long stretch of such dates to kick off December. The month starts with nine consecutive palindromes of at least five digits, beginning with 12/1/21 and ending with 12/9/21.
That comes after a run of 10 palindrome dates in January, which was headlined by the first palindrome date to fall on Inauguration Day, according to the almanac.
２１世紀中にはPalindrome Dateが３８日
更に、２１世紀中には、”３８”しかない！
となると、その半分以上は今年だったんだ。
何だか、とっても貴重な日、貴重な年を過ごしているような気がする。
