One-Time Dates

Previous pageReturn to chapter overviewNext page

In contrast to Recurring Holidays which have a complex structure of rules which apply to both past and future years, One-Time-Dates are a simple list of dates, which usually cannot be forecast, such as the list of trade fairs in a country, or listing of horse races, for example.

 

Each One-Time-Date is associated with a Name, an Abbreviation string and a Symbol string (though in the case of One-Time-Dates, these last 2 fields are often used for other information, as is shown in the example below).

 

 

One-Time-Dates can be viewed and modified from the second tab of the Holidays Manager.

 

 

The toolbar at the top of the One-Time Dates tab is composed of 2 elements.

 

At the left are buttons to Add, Delete or Modify One-Time-Dates.

 

The More... button displays a drop-down menu from which additional One-Time-Dates tools are available, such as Copying between Sets, Exporting, Importing and Purging.

The Navigator can be used to move the grid to a specific date range (note that if you scroll the grid manually , then the values in the Navigator are automatically updated).

 

Where do One-Time-Dates fit in ?

 

When you generate holidays, Q++ uses the holidays rules of each holidays set to calculate the occurrence of each recurring holiday for each year. Then Q++ adds the list of one-time dates to this list. By the time Q++ looks at the generated holidays to replace tokens during diary generation, the distinction between "recurring" and "one-time" has disappeared. One-Time Dates are displayed using the exact same tokens as Recurring Holidays. If a recurring holiday and a one-time date belonging to the same holidays set occur on the same date for a given year, with the same priority, then the recurring holiday will appear first (for more details, see the ordering of holidays).
