How this service works

Timezone converter, world clock, date math & meeting scheduler for AI agents. Pay-per-call x402 endpoints (USDC on Base).

Output

A JSON object containing a 'result' field with 'datetime' (ISO 8601 string with UTC offset applied, e.g. '2026-10-25T12:00:00+01:00') and 'timezone' (IANA timezone identifier, e.g. 'Europe/Madrid').

Example use cases

Trial expiry deadline calculation

“Our free trial starts on March 15th 2026 — what exact date and local time does it expire after 30 days, shown in America/New_York time?”

Contract notice period deadline

“I need to give 90 days notice before cancelling a contract that I want to end by December 31st 2026 — what's the latest date I can send the notice, in Europe/London time?”

Sprint end date planning

“Our two-week sprint kicks off on Monday May 4th 2026 at 9am in Asia/Tokyo — what is the exact datetime when the sprint ends 14 days later in that same timezone?”

When to prefer

Choose this endpoint when you need to perform arithmetic on dates or datetimes — adding or subtracting days, weeks, months, or hours — and want the result expressed in a specific IANA timezone with a correct UTC offset. Prefer it over simple timezone conversion endpoints when the core task is shifting a date by a duration rather than just re-expressing an existing timestamp in another zone.

Side effects

Invalid or unrecognized IANA timezone identifier returns an error
Malformed base datetime string causes parse failure
Negative or zero duration with ambiguous direction may return unexpected result
Missing required parameters (base date or offset) result in 4xx error
Payment not attached or insufficient USDC balance returns 402 Payment Required
