The Circle Bridge in Copenhagen, Denmark It’s Pi Day! Well, not that mouthwatering and cherry or berries filling pie, it's the day we celebrate the mathematical constant π. This day was chosen since today’s date (March 14) expressed numerically (in US format) matches the number’s first digits, 3.14. Pi represents the ratio of a circle’s circumference to its diameter. It can be used to compute the area and circumference of a circle, such as the circles that make up the bridge we're looking at here in Copenhagen. (Who said maths wasn't useful in the real world?) Many towns, schools, and museums mark the day with festivities based around mathematics and, of course, serving pie. We can’t think of a more delicious way to study geometry.

Today is “Hina Festival”. “Hina Doll” It is a spring festival originally transmitted from China as "Kami". I t is called "peach festival" because it is performed at the time when peach blossoms bloom ... Originally, before the Heian period (almost 1,000 years back), it was performed regardless of gender in the same way as the Dango festival, but it gradually became a girl's festival. The custom of this day is to display dolls on a red carpet. The dolls with dresses of Emperor and Empress are placed at the top and the ladies with ministers are in lower rows of the shelf. It is said that the ebb and flow of the evil to the dolls and the doll play of the girls were linked. The Japanese are a bit superstitious here. They believe that if you're a girl and fail to take the dolls out of the shelf right after the festival, no one is going to marry you for a long period of time.  So hurry up girls!  Put the dolls away!
