常见问题

Date Math 安全吗？

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前，请先看看这个服务器要求哪些权限，并使用只具备所需权限的密钥。

它需要哪些密钥或代码？

注册中心没有列出必需的密钥，不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端？

它在作者的云端运行。通过互联网连接，无需安装，但你发送的内容会经过作者的服务器。

它还在维护吗？

GitHub 仓库最后更新于–，最新版本（1.2.0）于今天进入注册中心。

哪些应用可以使用它？

支持 MCP 的应用，例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接，所以接受远程 MCP 服务器的应用也可以使用，例如开启开发者模式的 ChatGPT。

有什么可以替代它？

Date Math

Exact date and time math for AI agents, paid per call. LLMs are unreliable at business days, DST, recurring schedules and holiday calendars. Date Math gives them deterministic answers over HTTP or MCP.

Price: $0.001 per call in USDC on Base, via x402
Access: no signup, no API keys
Base URL: https://date-math.datemath.workers.dev
MCP endpoint: https://date-math.datemath.workers.dev/mcp (Streamable HTTP)
Docs for agents: /llms.txt · /openapi.json

Tools

HTTP (`POST`, JSON body)	MCP tool	What it does
`/v1/diff`	`date_diff`	Days, weeks, months and business days between two dates. Pass `country` to skip its public holidays.
`/v1/add`	`date_add`	The date N days, weeks, months or business days before or after a date
`/v1/convert`	`timezone_convert`	Converts a time between IANA time zones (DST-aware)
`/v1/info`	`date_info`	Weekday, ISO week, quarter, day of year, leap year
`/v1/holidays`	`public_holidays`	Public holidays for 207 countries, 2000–2050
`/v1/overlap`	`working_hours_overlap`	When working hours overlap across time zones (meeting slots)
`/v1/cron`	`cron_schedule`	Explains a cron expression and lists its next runs in any zone
`/v1/parse`	`parse_date_text`	"next Friday at 3pm" → an exact ISO datetime
`/v1/city`	`city_time`	City name → time zone and local time (7,000+ cities)
`/v1/recurrence`	`recurring_dates`	Expands an iCal RRULE ("every 2nd Tuesday") into dates
`/v1/business_hours`	`business_hours_deadline`	SLA deadline N working hours from now, or working time elapsed

Every response is a JSON object. Errors look like {"error":{"code","message"}}. Full schemas and examples are in /openapi.json.

Examples

# Unpaid call → HTTP 402 with payment terms in the PAYMENT-REQUIRED header

curl -i -X POST https://date-math.datemath.workers.dev/v1/business_hours \ -H "Content-Type: application/json" \ -d '{"start":"2026-11-06T16:00","hours":2,"timezone":"Asia/Manila","country":"PH"}'

Request body	Result
`/v1/business_hours` `{"start":"2026-11-06T16:00","hours":2,"timezone":"Asia/Manila"}`	`"deadline":"2026-11-09T10:00:00+08:00"` (Monday)
`/v1/add` `{"date":"2026-12-22","business_days":5,"country":"PH"}`	`"result":"2026-12-31"` (skips Christmas and Rizal Day)
`/v1/overlap` `{"timezones":["Asia/Manila","Europe/London"],"date":"2026-11-10","work_end":"18:00"}`	One window: `09:00–10:00Z`
`/v1/recurrence` `{"rrule":"FREQ=MONTHLY;BYDAY=2TU","start":"2026-01-01T10:00","timezone":"Asia/Manila","count":3}`	Jan 13, Feb 10, Mar 10 at 10:00 +08:00

Paying from code

Any x402 client pays automatically. With the official TypeScript client:

import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";

import { ExactEvmScheme } from "@x402/evm"; import { privateKeyToAccount } from "viem/accounts";

const pay = wrapFetchWithPaymentFromConfig(fetch, { schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(privateKeyToAccount(process.env.KEY as 0x${string})) }], });

const res = await pay("https://date-math.datemath.workers.dev/v1/city", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ cities: ["Cebu", "London"] }), }); console.log(await res.json());

The wallet needs USDC on Base. No ETH is required, because the facilitator pays gas.

Using it over MCP

Endpoint: https://date-math.datemath.workers.dev/mcp (Streamable HTTP, stateless)
Listing tools (tools/list) is free.
Each tool call costs $0.001 via x402 MCP. Payment travels in the tool call's _meta, and x402-aware clients handle it automatically:

import { createx402MCPClient } from "@x402/mcp";

import { ExactEvmScheme } from "@x402/evm/exact/client"; import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js";

MCP clients without x402 support can list the tools, but calls return "Payment required".

Run your own copy

The service is a single Cloudflare Worker and fits the free plan: every tool uses 0–6 ms of CPU per call.

cd worker

npm install npm test # 99 tests npx wrangler login npx wrangler deploy

Set your own wallet and price in worker/wrangler.toml:

Setting	Meaning
`PAY_TO`	Your wallet address. Leave empty to make every endpoint free.
`PRICE`	Price per call, e.g. `$0.001`
`X402_NETWORK`	`eip155:8453` (Base) or `eip155:84532` (Base Sepolia, for testing)
`FACILITATOR_URL`	Defaults to PayAI: no key needed, and it pays gas

Optional secrets (set with npx wrangler secret put):

`CDP_API_KEY_ID`, `CDP_API_KEY_SECRET`: settle through Coinbase's facilitator first.
`POCKET_PREFIX`: a private, unpaid path for trusted relays.

To check your deployment against x402scan's discovery rules, run node tools/x402scan-audit.mjs https://your-worker.workers.dev.

How it's built

Stack: Hono on Cloudflare Workers, plus @x402/hono and @x402/mcp.
Discovery: OpenAPI with x-payment-info, /.well-known/x402, x402 Bazaar metadata on every 402, and llms.txt.
Precomputed data: the holiday and city tables are built at build time (worker/scripts/build-*.mjs), so lookups are O(1) per request.
Time zones: UTC offsets come from cached Intl formatters and a week-segment cache. They're tested against direct lookups for tricky zones (Morocco, Lord Howe, Chatham).
Cron: a built-in engine (worker/src/cron.ts), checked against cron-parser on 400 random expressions.
Workers-specific shim: x402's Bazaar route validator uses Ajv code generation (new Function), which Workers blocks. wrangler.toml aliases it to a no-op shim (worker/src/shims/bazaar.ts).

Data and license

Code: MIT, see LICENSE.
Holiday data: derived from date-holidays (CC BY 3.0). Lunar or government-proclaimed dates are rule-based estimates.
City data: derived from city-timezones (MIT), based on Natural Earth (public domain).
