Qlik Custom Calendars (for Qlik Sense & QlikView)

Qlik Sense and QlikView both handle dates via list boxes (or Filter Panes in Sense). The conventional approach to providing users with date selectors is to create a master calendar and create list boxes in the application to select things such as “Year”, “Month” and “Quarter”. This works well enough, and it addresses issues with missing dates in the data. However, in many cases a more friendly and ergonomic date selector is desirable. Custom Calendars in Qlik load scripts can provide a better way for users to select date ranges. A custom calendar can allow users to select things such as “This Month” or “Last Week” or “Last Two Years”. Such scripting can be combined with a Master Calendar to ensure there are gaps in the date ranges. The following script creates a custom calendar in Qlik Sense or Qlik View load scripts.
