Plans to add MonthDay and YearMonth?

Are there any plans to add the structures MonthDay (represents a birthday) and YearMonth?

As in the EcmaScript TC39 temporal proposal:

Or the excellent JSR-310 spec:

https://docs.oracle.com/javase/8/docs/api/java/time/package-summary.html

The idea of year-month fits well with the most excellent calendar_interval by @wojtekmach. In general the principle of intervals is a very clean abstraction for periods of time (especially the references to Allen’s Interval Algebra).

Typically the idea would be that you (or any community member) makes a proposal here. That gets it good exposure, often a lot of good discussion. And then if there’s support for the proposal you (or any other volunteer) gets developing.

Not read those specs before, thanks for posting. And hadn’t thought about month-day except in the context of recurring dates - which I suppose is the main use case?
