The Longest Date String

Given a date format like “Thursday, January 21, 2010” and limited space to drop in this string on a page, what is the maximum width of this string as rendered in Georgia or Helvetica/Arial?

Longest day of the week: Wednesday
Longest day of the month: 22–30 (30 is a hair wider in Georgia)
Longest month of the year: September
Longest years: 2002–2009, 2020 (Yay for a “short” next decade?)

Therefore, the hypothetical longest date string is “Wednesday, September 30, 2009”. Then I discovered that September 30, 2009 is actually a Wednesday. Neat.
