Appended to a day cell borrowed from a neighbouring month, after the date itself. The date already names its own month, so this only has to say that choosing the cell moves the grid there, which the fading says to a sighted user and nothing says to a screen reader.
What a day the institution is shut for is called, whether the week says so or an event does. A calendar writing a day out leads with this or with workingDayText.
The datePickerTitle family again, worded for a picker showing the Gregorian calendar.
Shown for a month whose every day carries nothing.
Shown for an open day carrying nothing at all.
What a day off the weekly rule alone produces is called, said after closedText so a Saturday reads as closed and then as why.
What an ordinary open day is called, the counterpart of closedText.
