If a holiday was not celebrated in a given year, it will not
show.

Includes complete Java source code to calculate when the
holiday occurs in a given year, when it was first
celebrated, when first proclaimed, the rule for how it is
calculated in words and an authority to go to for more
information.

Also calculates the nearest weekday to any given holiday,
when you actually get the day off. This is what I refer to
by the term "shifted". Boxing day has special shift
handling.

Shareware that may be freely distributed and used for
any purpose except military.

In the source are methods that can also be used to calculate
how many business days were between given dates. It is quite
easy to specify which days you want considered as holidays
using methods like addHoliday where you specify the date or
the name of the Holiday, addAmericanFederalHolidays and
addWeekDaysAsHolidays.

The main holiday still missing is Chinese New Year.
