I brought it up because this article used to mention this date from January 2005 through August 2010 It s not all that obvious that the date in 1592 could not have been observed As 2015 draws near there may be some debate over which date is the best If this were mentioned in the article it may correct any misconceptions people may have or get people thinking about what they are really celebrating Some external references to the ultimate pi day in 1592 include The ultimate pi day occurred on March 14 1592 at 6 54 AM The ultimate pi day in history occurred on March 14 1592 at 6 53 59 AM I doubt the celebration will be quite as extravagant as the pi day of 1592 Of course if this were 1592 none of us would be celebrating something as frivolous as Pi Day Pi Day is March 14 1592 The perfect pi day was in 1592 It s been said the only real Pi Day was March 14 1592 I wonder if anyone paid attention in 1592 when the date was 3 14 1592 a full on in your face pi day Pi day was on March 14 1592 Some have dated the first Pi day celebration to March 14 1592 at 6 53 58 This is incorrect The ultimate pi moment occurred on March 14 1592 at 6 53 AM and 58 seconds note that 1592 was a better year for Pi Day
