Outdated info about Excel's date systems

[allie-tatarian]

What is the problem?

In the Dates as Data lesson, there is a grey box titled "Excel's Date Systems" that warns users that Excel for Macintosh defaults to a 1904-start date system, instead of the 1900-start that Windows uses. This is no longer true, and Excel for Mac now defaults to a 1900-start date system just like Windows, according to Microsoft.
