## What you need to know

### How should dates be displayed internationally?

Display an unambiguous localized format and include month names or ISO-style ordering where confusion is costly. Store dates in a canonical representation.

### How should time zones be handled in ecommerce?

Store event timestamps consistently, retain the relevant zone, and display them in the context that matters; customer, store, warehouse or carrier. Always label deadlines that cross zones.

### How should weight units change by market?

Show the unit customers expect while retaining a canonical shipping weight. Conversion and rounding must not alter the carrier value or regulatory declaration.

### How should measurement units change by market?

Localize length, volume, temperature, and size information when it helps decisions, but preserve original specifications and state units beside every value.

### How should decimal and thousands separators be localized?

Use locale-aware formatting rather than replacing punctuation in text. Parsing and storage should use canonical numeric values independent of display separators.

### How should currency symbols and formats be displayed?

Format symbol position, spacing and decimal digits according to currency and locale, and include a currency code when the symbol could be ambiguous.

### A quick store check

Switch locale and time zone and verify one price, dimension, deadline and event timestamp remain unambiguous.
