That's wrong if you do the math yourself. Try this: http://www.wolframalpha.com/input/?i=Sept+30%2C+1984+to+today+in+days http://www.wolframalpha.com/input/?i=S

It says 9855 days, which is 365 * (2011 - 1984), which is obviously not right and missing leap years.
- abduhl 15y agoThe correct formula that Wolfram should be using here is floor((cur_yr - old_yr)x365.25), assuming you are interested only in the recent past where the 365.25 holds true. As an aside, floor(365.25x(2011-1984))+138 gives 9,999 days elapsed which would make today the 10,000th day, as stated by Zuckerberg. EDIT: this formula only works when you begin on a day after a leap day during a leap year, thanks hennypenny
- hennypenny 15y agoYour formula doesn't work. There have been 7 leap days including 1984. The date of the leap day is relevant to your formula because if he were born on Jan 1 there would be a difference in your result. Also, May 14 plus 138 days would have been September 29, not Sept 30.
- abduhl 15y agoThis has to do with when you take the starting point for the day I would assume. Also, I got the number from Wolfram: http://www.wolframalpha.com/input/?i=May+14+1984+to+September+30+1984+in+days http://www.wolframalpha.com/input/?i=May+14+1984+to+Septembe...
- hennypenny 15y agoIn the this case 'to' means 'through' and is inclusive of all the days. By adding the difference we do not twice count the number we arrived at from the first part of your calculation.
