Quarter picker support

[pdreij]

We are currently using useDatePicker from React Aria in our forms, but we now have a requirement to allow users to select a quarter (Q1–Q4) rather than a specific date.

From reviewing the existing date APIs, it appears that the current abstractions are centered around day-level selection. While it may be possible to approximate quarter selection using lower-level primitives like useCalendar, it doesn’t seem to map cleanly to the interaction model of a typical quarter picker.

A quarter picker differs in a few ways:

• The selection unit is a quarter, not a day.
• The UI typically presents four selectable options per year.
• The value represents a logical quarter (or quarter range) rather than a single date.
• Accessibility semantics and keyboard behavior would likely differ from a traditional date grid.

Is quarter-level selection considered in scope for React Aria / React Spectrum date components?

If not currently supported, would it make sense to introduce first-class support for quarter selection — either via an extension of the existing date picker abstractions or a dedicated hook/component?

This is a fairly common requirement in enterprise reporting workflows, and having an accessible, internationalized primitive for it would be valuable.
