Holidays: Time Windows


We can deliver forward data out to the year 2200, as well as extensive history. For the forward-looking data, your window of time can be expressed in days, months or years.
Two types of data window--Rolling and Static
  • A Rolling window is expressed relative to the delivery date and automatically shifts forward with the passage of time. For example, a customer with a 5-year Rolling window who gets a delivery on May 4, 2015 would receive data covering the period from May 4, 2015 to May 4, 2020. If this customer receives another delivery on May 18, 2015, the data would cover May 18, 2015 to May 18, 2020.
  • A Static window, on the other hand, always starts on January 1 of one year and ends on December 31 of another. The Static window rolls forward once a year in late January or early February. For example, a customer who gets a 5-year Static window would receive data for the period January 1, 2015 to December 31, 2019 for deliveries made on both May 4 and May 18, 2015.
When choosing between them...
  • All windows under two years must be Rolling.
  • Rolling windows entail a bigger data volume (except with the Deltas layout). This is because, in order to ensure that you have the same end date for every financial center, all deliveries must consist of a full set of fresh data for every financial center that you license. By contrast, when issuing an update to Static window customers, we normally deliver data only for the affected centers.
Keep in mind that you will also receive pre-scheduled deliveries to protect against “end-date creep.” This is the phenomenon whereby the end-date of your window moves closer with the passage of time. For example, if your last delivery covered the period May 1, 2015 to June 1, 2015, end-date creep means that by May 10 you would only have 21 days of forward data.

To protect against end-date creep, we provide pre-scheduled refreshes of data according to a timetable of your choice. The most popular frequencies are annual, quarterly, monthly and semi-monthly.
