A developer has released a remote MCP (Model Context Protocol) server that gives AI agents exact date and time calculations, including holiday lookups, business-day counting, time zone conversion, working-hour overlap, cron schedules, and RRULE recurrence rules.

A deterministic date-and-time server gives AI agents exact calendar answers

A new remote MCP server lets agents compute holidays, business days, time zone conversions, working-hour overlaps, cron schedules and RRULE recurrences instead of estimating them.

Deterministic tools, same input returns same output

207

Countries covered by the holiday data (per the creator)

7,000+

Holidays listed; counting method not specified

Tool count as stacked blocks

Each block is one of the 11 deterministic tools.

11 tools
Holiday lookup, business-day counting, time zone conversion, working-hour overlap, cron, and RRULE handling, all computed rather than generated.

How an agent gets a computed answer

1. Question
e.g. business days in a country

2. Tool call
agent routes to the server

3. Computed result
same input, same output

4. Answer
grounded, not estimated

Flow runs left to right. The model hands off arithmetic; it no longer guesses it.

Why it helps

Targets known LLM weak spots in calendar math
Cron and RRULE support for reading and writing repeating schedules
Works with any MCP-compatible client, no local install

What remains unverified

Coverage claims have not been independently checked
How the 7,000 holiday figure is counted is unspecified
Pricing, licensing, rate limits, and data upkeep were not disclosed
