Someone calculated pi to 2.7 trillion digits!

The mathematical constant pi, more often referred to as the Greek letter π, is the ratio of any circle to its diameter, and has an infinite amount of numbers. Usually written as simply 3.14, it has now been calculated to its 2.7th trillion digit!

The 2.7 trillion digits is 123 billion more digits than the previous record. The prior record had been calculated on a super computer, but Fabrice Bellard, who calculated the digits, says he used a very simple method and common computer. Bellard says that although it was fun to break the record, finding pi was simply a way to test his method to see if it could be used for other mathematical purposes.

In Japan, Valentine's day is usually the female's responsibility. White Day, on March 14th, is the man's turn to reciprocate

On Valentine's day, women give men chocolate gifts. This is supposed to be an expression of love, courtesy or social obligation. A hand-made chocolate is considered to be a sign that the man who receives it is the woman's "only one."

Starting in 1978, White Day was promoted by the National Confectionary Industry Association. It is supposed to be the answer day to Valentine's. Traditional gifts on this day are cookies, jewelry, white chocolate, white lingerie and marshmallows. The often cited rule is that the gift on this day should be three times as expensive as the one received on Valentine's.

There are actually 2 St. Valentines whose feast day it is today.

Seems that the apostrophe on St. Valentine's is written one letter too soon. While numerous early Christian martyrs were named Valentine, two are being celebrated by the Catholic Church today. One is Valentine of Rome, who was a Roman priest martyred around the year AD 269. His relics are displayed in a Church in Rome and Dublin.

The second is Valentine of Terni, who was the bishop of Interama around the year AD 197. He was martyred by Emperor Aurelian. Both Saints were buried on Via Flaminia, in Rome. Valentine of Terni's relics are in display at the Basilica of Saint Valentine in Terni. There is a third St. Valentine mentioned in early martyrologies but not much is known about him. 

Interestingly, neither Saints' histories mention any romantic elements in their biographies. The first romantic association with Valentine's Day didn't happen until the year 1382.

A study found a significant increase in the number of births during St. Valentine's day

C-sections are allowing women to have their babies on their schedule nowadays. Because of that, it's not surprising that women may be picking certain dates over other dates to have their kids. A recent study of US birth certificates on a 10-year period suggests that women; whether through c-section or other more natural means, might be picking Valentine's day to have their kids.

The study found that there were 4% more birthdays on Valentine's day than there were on any day in the surrounding 2 weeks. Interestingly, they found a similar change on another holiday, months later. There were 5% LESS births on Halloween than in any other day surrounding it.

India celebrates Children's Day on November 14th, 9 months after Valentine's day

Although completely unrelated to today's holiday, it's a funny coincidence to that India would celebrate a holiday dedicated to emphasize the importance of giving love and affection to children.

The holiday in India is celebrated that day because it's the birthday of the country's first Prime Minister, Jawaharial Nehru. Indian kids called him Uncle Nehry. His affection for kids inspired the holiday.
