Creating Calendars

To set up a system of calendars for your business, you need to plan which calendars are needed to meet your business requirements.

Note: Note that you can also create and manage calendars using the Calendar gadget in TIBCO Openspace. See "Using the Calendar Gadget" in the TIBCO Openspace User’s Guide for more information on calendars in Openspace.

First, since a Base calendar is associated with a time zone, you will want at least one Base calendar for each time zone in which your business operates. If you have multiple offices or other business units in the same time zone but with different working weeks—perhaps in different countries, or perhaps offices that work five-day weeks and transport depots that work six or seven days—you will want more than one Base calendar with the same time zone, but different working-days properties.

For example, in an environment that provides 24-hour support, you might have:

  • An Early Base calendar, defining working hours as from 06:00 to 14:00 per day, which would be referenced by the organization unit EarlyShift,
  • A Late Base calendar, defining working hours as from 14:00 to 22:00, which would be referenced by the organization unit LateShift,
  • A Night Base calendar, defining working hours as from 22:00 to 06:00, which would be referenced by the organization unit NightShift.

Alternatively the same functionality could be provided by defining a 24-hour working day on the Base calendar and using three overlay calendars to modify it.

You might also use Overlay calendars:

  • On a national level, to define public holidays, if you choose not to do so in the Base calendar,
  • To restrict working hours for shifts. For example, a claims assessment department in an insurance company works from 08:00 to 20:00. But no individual works a 12-hour day; the department is divided into two shifts that work 08:00 to 16:00 and 12:00 to 20:00. Therefore the department uses:
    • a Base calendar that defines the whole working day, that is referenced by the claims assessment department Organization Unit,
    • two Overlay calendars, that each exclude the non-working hours for one of the shifts, and each of which is referenced by the appropriate shift’s Organization Unit.

While organizational entities such as organization units or groups will use these Overlay calendars, your system of calendars need not correspond directly to the organization model. The same Overlay calendar might be referenced by several different organizational entities.

Having planned your calendars, you can follow a procedure similar to that shown in the figure below.

Creating Base and Overlay Calendars

Procedure

  1. Use listTimeZones to generate a list of the permitted time zone values to be assigned to Base calendars.
  2. Create an initial Base calendar. The illustration above shows the use of saveCalendar. You can set the time zone of the new calendar, using one of the values returned by the listTimeZones response. Use the working-days parameter to specify the normal working hours for each day of the working week.
  3. You can use copyCalendar to copy your initial Base calendar to create a second.
    Tip: Note that copyCalendar does not enable you to change the time zone of the new calendar. If your strategy is to have a Base calendar for each time zone in which your business operates, for example, you could subsequently use saveCalendar to change the time zone of each copy.
  4. Use saveCalendarEntry to create the entries on your second calendar.
  5. Repeat step 3 to step 4 as necessary until you have all the Base calendars you want.
  6. Use saveCalendar to create an Overlay calendar.
  7. Create another Overlay calendar using copyCalendar to copy the first one.
  8. Create the entries on your second Overlay calendar using saveCalendarEntry.
  9. Repeat step 7 to step 8 as necessary until you have all the Overlay calendars you want.
