How this service works
Show an instant in an IANA timezone and locale with full/long/medium/short styles; DST-aware, with UTC offset.
Output
Returns a formatted date/time string for the requested locale and timezone, along with the resolved locale, IANA timezone, UTC offset, epoch milliseconds, calendar system, numbering system, CLDR/ICU/Unicode versions, and a degraded flag if fallback formatting was used.
Example use cases
Localized event time for global users
“I have an event at 2025-03-20T18:00:00Z — can you show that as a full date and full time in the Europe/Berlin timezone using de-DE formatting?”
Receipts with local date display
“Format the order timestamp 1718459400000 (epoch ms) as a medium-style date with short time in Asia/Tokyo timezone for a Japanese customer, using the ja-JP locale.”
Scheduling assistant time display
“What does 2024-11-05T09:00:00Z look like as a long-style date in the America/Los_Angeles timezone for an en-US user — and what's the UTC offset at that moment given DST?”
Technical details
Endpoint
GEThttps://locale-tools.x402tookit.com/format-date?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fully localized, DST-aware date/time string for a specific IANA timezone and BCP47 locale — especially when you need the UTC offset, calendar system metadata, or CLDR version alongside the formatted output. Prefer this over manual string formatting when serving international users who require culturally correct date presentation.
Side effects
- Invalid or unrecognized IANA timezone returns an error or falls back to UTC with degraded=true
- Malformed ISO 8601 or out-of-range epoch value returns a parsing error
- Unknown BCP47 locale tag may fall back to en-US with degraded=true
- Date string longer than 40 characters is rejected
- Timezone string longer than 60 characters is rejected
