Suggestion additional text for this help page:
If you only need to display a string showing the day of the week, also consider using the date formatting options.
EG: When using Calc and for a cell containing a date value,
from the menu: Format > Cells > Date
Then use a custom format of DDD to show the day of the week in the style of "FRI" or use DDDD to show the day of the week in the style of "Friday"

I think the suggestion introduces a digression. The function returns explicitly a string with the week day name. The suggestion above keeps the cell contents (numeric) and changes only the displayed format.
OTOH, the suggestion is well suited for a User Guide on the topic.
