Use a Poland locale in a product
When content is written in Polish, use the lang tag below to describe the text. The Intl locale selects regional formatting. This is one example from the table, not a claim about every visitor's language preference.
<html lang="pl">
new Intl.NumberFormat("pl-PL").format(1234567.89);Compare number and date formatting
These examples use 1234567.89 and the fixed instant 2026-01-15T13:45:00Z, with dates displayed in UTC. Intl computes the results when this site is built; your browser and locale-data version may differ. Unsupported tags are identified instead of showing default-language output.
| Locale | Number | Date | Currency |
|---|---|---|---|
pl-PL | 1 234 567,89 | 15 stycznia 2026 | PLN: 1234,50 zł |
de-PL | 1.234.567,89 | 15. Januar 2026 | PLN: 1.234,50 PLN |
csb-PL | Unsupported in this build | Unsupported in this build | PLN: Unsupported in this build |
lt-PL | 1 234 567,89 | 2026 m. sausio 15 d. | PLN: 1 234,50 PLN |
Currency examples use the fixed value 1234.5. SIX and CLDR snapshot: 2026-09-26. Specify each currency explicitly; formatting is not an exchange rate.
new Intl.NumberFormat("pl-PL", { style: "currency", currency: "PLN" }).format(1234.5);Before adopting a tag, run Intl.NumberFormat.supportedLocalesOf() and Intl.DateTimeFormat.supportedLocalesOf() in your target runtime. A locale does not select a time zone or translate interface text; specify currency explicitly when formatting money.
