What is it?
Your browser language (or locale) is a setting that tells websites which language you prefer to read. It is transmitted via an HTTP header called "Accept-Language" and is formatted as a language code and region (e.g., "en-US" for English as used in the United States).
Why this matters
Multilingual websites use this metric to automatically serve translated content, adjust date formats, or load regional currency symbols without requiring you to manually select a country from a dropdown menu.
Practical Use Cases
- Internationalization (i18n) Developers verifying that their language detection logic handles different regional dialects correctly.
- Users troubleshooting why a global website keeps forcing them to view the page in the wrong language.
- Translators testing localized web interfaces.
