India Date and Number Format

In short India writes dates day, month, year — 23 July 2026 is 23/07/2026 — and numbers as 12,34,567.89. India groups the last three digits and then in twos: 12,34,567.89 rather than 1,234,567.89. That is the lakh and crore system — a lakh is 1,00,000 and a crore is 1,00,00,000 — and it is the one grouping pattern here that breaks any formatter assuming a comma every three digits. 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 digit grouping here is 2,2,3 rather than the usual three-at-a-time, so any code that assumes a separator every three digits produces the wrong figure. 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.
