MORE INFORMATION

Page 69: 1900 Is Not A Leap Year

On Page 69, in the first paragraph, the last sentence states that 1900 was a leap year, so it had 366 days. This information is incorrect. This sentence should be deleted.

In addition, it should be noted that the year 1900 is not a leap year as the illustration at the top of the page indicates by the number 366. It should also be noted that Microsoft Excel treats 1900 as a leap year, and that this algorithm was adopted to maintain compatibility with dates in Lotus 1-2-3, and is by design.
