Javascript Date.getFullYear() deprecates Date.getYear()

Apparently this is old news to intelligent developers. I am an idiot. So it was news to me :)

The javascript method Date.getFullYear() depreciates Date.getYear(). Some browsers will simply return the number of years since 1900 if you use Date.getYear(). So use Date.getFullYear() to include dates.
