Pi Day

Today is White Day that men give women gifts for their Valentine's chocolates in Japan.

However, today is also Pi Day.

In 2009, Pi Day was formally established by the United States House of Representatives.

In mathematics departments of some universities, anniversary parties seem to be held in this day.

Also, right now, I am submitting this post on March 14, 15:09.

I chose the time closer to pi among Pi Day.

By the way, there is an ultimate pi day (time), which is 3/14/1952 6:53:58.

円周率の日

今日、日本はバレンタインのお返しをするホワイトデーです。

しかし、今日は円周率の日でもあります。

円周率の日は、2009年にアメリカ合衆国下院によって正式に制定されており、一部の大学の数学科ではこの日のパーティをするようです。

そしてこの投稿をしている今は、3月14日の15時9分です。

円周率の日の中でも、より円周率に近い時間を選びました。

また、究極の円周率の日（時間）として、1592年3月14日6時53分58秒があります。

White Day seems like a fun tradition to have in the US as well. In my university, the mathematics professors would bring pie for their classes on Pi Day. :)

円周率の日があるんだ！
初耳です。勉強になりましたヽ(*´∀｀)ノ
