Switzerland Date and Number Format

In short Switzerland writes dates day, month, year — 23 July 2026 is 23.07.2026 — and numbers as 1'234'567.89. Switzerland groups thousands with an apostrophe: 1'234'567.89. WHICH apostrophe depends on how current your software is, and this is the only row in the table where that is true. CLDR used the right single quotation mark U+2019 for years and has since moved to the plain ASCII apostrophe U+0027 — Chrome 148 gives U+0027, Node 22 still gives U+2019. Both are in circulation, they are different bytes, and they look near enough identical on screen that no diff a human reads will show it. A Swiss figure that refuses to parse is almost always carrying the separator your parser was not expecting rather than a broken number. Two general points apply to reading anything from here. First, the date order and the number format vary independently: 30 of the 39 locales checked share this date order, and that tells you nothing about how they punctuate numbers. Britain writes dates the European way and numbers the American way; South Africa writes English and formats numbers continentally. Second, the separator characters matter more than they look. Six different characters group thousands across these locales and three of them are invisible or near-invisible, so a figure that pastes into a spreadsheet as text usually has a separator the spreadsheet did not recognise rather than anything wrong with the number. Every value on this page was extracted from Intl rather than transcribed, and the page re-checks the thousands separator against your own browser when it loads — CLDR revisions land in browsers and in Node at different times, so a static table can be right when it is written and out of date by the time it is read.
