About Local Time Formatting
Time formatting varies by locale and timezone. The same instant in time can be displayed as "7/25/2026, 3:00:00 PM" in en-US or "25.07.2026, 15:00:00" in de-DE. This tool shows how every locale-sensitive format changes when you switch locale or timezone.
What Changes With Locale?
Locale affects date/month ordering (M/D/Y vs D/M/Y), month and day names, 12h vs 24h clock preference, digit grouping (commas vs spaces vs periods), decimal separators, and the display language for timezone names. Formats like ISO 8601, RFC 2822, and Unix epoch are locale-invariant — they look the same regardless of locale.
All formatting uses the browser's built-in Intl.DateTimeFormat and Intl.RelativeTimeFormat APIs.
