Everything happens from **Settings > Language and region**: you choose your interface language, then adjust the date format, time format, first day of the week, currency, and number format. Format changes apply immediately across the whole app.

## Change the interface language

Select your language from the dedicated menu. This change applies once you save the page, and updates every label across your dashboard.

## Adjust the formats

A dedicated, collapsible section groups the regional settings:

- **Date format** and **time format** (12h or 24h).
- **First day of the week**, useful for how your calendar displays.
- **Currency** and **number format**.
- **Units of measurement**.

Unlike the language, these format settings apply in real time as soon as you change them, without waiting for a save: you see the effect on the app immediately as you adjust.

## Edge cases

**The date format shown doesn't match what you expected.** Check the format selected in the Regional formats section, it drives the display across the whole dashboard, including the calendar and invoices.

**You can't find a setting for your clients' default language.** This option isn't available in the interface yet: it will come in a future update.

## What's next

If you use message templates to communicate with your clients, keep in mind that their language is set separately, within the templates themselves.
