Working with time is always hard and we often mess up our time logic.

My guess on why we always have a hard time is that we deal with a concrete clock too soon. I suppose we should deal with time in a more declarative way by using human terms and resolve to a concrete PointInTime at the end of our processing.

Example to list the days of february:

Calendar::of($clock)
    ->year(2024)
    ->february()
    ->days(): Sequence<Day>;

For example this sequence is not fixed as it changes on leap years.

If done correctly the API would allow to ease testing code working on a span of time.
