Note that both the official day of the holiday, and the day it is observed by the US Government, are both listed (if different.)

The Chronos code used to generate the list is given below:

| holidays | 
holidays := SortedCollection sortBlock: [:a :b | a key < b key].
(Timeperiod yearStartingAt: (YearMonthDay year: 2006 month: January day: 1)) every: 1 daysDo: [:day |

    ifTrue: [holidays add: date->(Array with: semanticKey with: date dayOfWeekName)]].
