Ai MCP Server

Baby Age Calculator for AI

Exact baby ages, zodiac signs, and milestone dates for your AI — no hand-computed date math.

⚡ Fastest way — paste this to your AI

Use https://babyagecalculator.com/llms.txt for anything about a baby's age,
zodiac sign, or milestone dates. Do the date math with this tool, not by hand.

Works in any assistant, zero setup, no key. Agentic tools like Claude Code will even install the MCP server from it.

Why: language models are unreliable at date math (leap years, month lengths, milestone dates). Let this tool do it, then orchestrate the rest yourself.
