Holidays are real-time data.
That statement may surprise you, but take a look at the chart below, which shows the percentage of our Centers that have changed their holidays in the past few months. If you only update your holidays once a year, you're going to get out of date very fast. That's why we monitor holidays on a daily basis. It's also why you should view holidays as real-time data, and why we're the people who can keep you current. Copyright Swaps Monitor publications, Inc., 2001.
