Asunto: Re: [Tails-ux] New Greeter: need clarification of what the "Formats" option should do
Thanks for the thorough explanation.

From a user standpoint, I like (4), or if I understand it correctly, (2) making the choice 2-step, opt-in, where first the person chooses to match the UI language to their own preference (French), then sees the French calendar and opts to change that to Japanese format with a second control if they want to.

The main question I have is how many people would prefer to see, for example, a Japanese format calendar in Japan when they speak French. It seems pretty edge-case to me. Is the rationale that they want to do visual pattern matching with local other calendars?

I would think that the errors caused by unfamiliar calendar formats would outweigh the benefit of showing an unreadable local format. I know when I had a German wall calendar, for example, which starts the week on a different day than in the USA, I made errors in planning so often during that year that I had to hide the box-grid part of it. Very often, not having to do the extra mental translation is the better choice for UI controls. ("Don't Make Me Think")

Best wishes,

Susan
