is the calendar broken?

[Nic]

I did this:

    (progn
      (setq christian-holidays nil)
      (setq hebrew-holidays nil)
      (setq islamic-holidays nil)
      (setq solar-holidays nil)
      (setq bahai-holidays nil)
      (setq oriental-holidays nil)
      (setq all-christian-calendar-holidays nil)
      (setq all-hebrew-calendar-holidays nil)
      (setq all-islamic-calendar-holidays nil)
      (setq all-solar-calendar-holidays nil)
      (setq all-bahai-calendar-holidays nil)
      )

And then this:
  (list-holidays 2006 2006)

and I got this:

  Sunday, January 29, 2006: Chinese New Year (Bing-Xu)
  Tuesday, January 31, 2006: Islamic New Year 1427
  Wednesday, March 1, 2006: Ash Wednesday

  Thursday, April 13, 2006: Passover
  Friday, April 14, 2006: Good Friday
  Sunday, April 16, 2006: Easter Sunday

  Friday, June 2, 2006: Shavuot
  Wednesday, June 21, 2006: Summer Solstice 12:25pm (UTC)
  Sunday, July 9, 2006: Martyrdom of the Bab
  Saturday, September 23, 2006: Autumnal Equinox 4:03am (UTC)
  Saturday, September 23, 2006: Rosh HaShanah 5767
  Sunday, September 24, 2006: Ramadan Begins
  Monday, October 2, 2006: Yom Kippur
  Saturday, October 7, 2006: Sukkot
  Saturday, October 14, 2006: Shemini Atzeret
  Sunday, October 15, 2006: Simchat Torah
  Friday, October 20, 2006: Birth of the Bab
  Sunday, November 12, 2006: Birth of Baha'u'llah
  Saturday, December 16, 2006: Hanukkah
  Friday, December 22, 2006: Winter Solstice 12:21am (UTC)
  Monday, December 25, 2006: Christmas

Which, much to my suprise still includes quite a lot of holidays. Have
I got the wrong end of the stick with the way holidays work (it all
seems remarkably complicated to me) or do other people agree that
something looks broken?
