Many holidays are changed at very short notice

Unfortunately, the people who determine holidays often make changes with very little advance notice. We analyzed all holiday changes in the years 2000 to 2007 and found that 40% of the time they were made only seven or fewer days in advance. We also found that we received at least three months' advance notice less than one-third of the time.
