What it is
Seasonal work competes with the ordinary calendar, and without reserved capacity it is done in whatever time is left, which is why it is usually rushed.

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
