Date notation in widget toggle

Hi,

General settings -> Date Format

Hi,

Changed that but that does not work.
Settings > General > date format j F Y

But the widgets says e.g. “sep 23” instead of “23 sep”

Same here. Hope someone knows how to change this. Did a search, but couldn’t find the solution.
