::: 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"
