# 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.
## Want it installed for good?
