“In England, and English colonies and commonwealths, they typically date things: dd/mm/yyyy.” True, but on a hunch, when this was first released, I may have been the first person to find on the Wiki international date format page that Kenya is one of the few countries in the world that was listed as regularly using BOTH formats.
The original source data (from memory) came from IBM software manuals that were used to set up computer software formats by country around the world.
An Obot named Mystylplx immediately edited the Wiki page, but was reversed and locked for a time, but now all specific references to Kenya using two formats have disappeared from the text of the page except for the world map, which may have been harder for the Obot scrubbers to edit.
Kenya is still color-coded purple on the world map as a dual format country at this site:
There is a ready explanation for two formats in the fact that Kenya, when founded, was formed by the merger of two separate legal entities, Kenya Colony and Coast Province, which may well have used two different formats in their separate clerical cultures.
