# Almanac Time API

> Almanac Time API is a paid API for AI agents from almanac.locomot.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Performs time zone conversions, epoch lookups, time-diff calculations, business day counting, and holiday checks for a given instant and locale

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability almanac-time-api-1389c309
```

Example prompt: Convert 2025-03-15T09:00:00 from America/New_York to Europe/London and give me the UTC time and Unix epoch for that moment.

## When to prefer this

Use this endpoint when you need authoritative timezone-aware time conversion, Unix epoch lookup, business day calculation between two dates, or holiday detection for a specific country — especially when you need deterministic, database-version-stamped results rather than a simple language model guess about time zones or dates.

## Known failure modes

- Invalid or unrecognized IANA timezone name returns an error
- Malformed ISO-8601 datetime string causes a parsing error
- Unsupported country code for holidays returns an error or empty result
- Missing required parameters for the selected operation (e.g. no start/end for diff) returns a 400-style error
- Ambiguous epoch (seconds vs milliseconds) may produce unexpected results if the wrong magnitude is passed

## How this service works

Deterministic time/timezone truth: DST-aware zone conversion, transition times, business-day & holiday math, epoch<->ISO. Free sample, no payment required: GET /play/time

## Output

Returns a JSON object with the operation type, the converted time in the target timezone (with offset details), the original time in the source timezone, the same UTC instant, a boolean confirming it's the same instant, the Unix epoch in seconds, and the timezone database version used.
