Project 1: Temporal Pattern Analysis in Birth Data Distributions
================================================================
Analyzes whether birth times cluster around certain planetary configurations
using REAL birth data from CDC WONDER and AstroDatabank.
DATA SOURCES:
- CDC WONDER Birth Data: https://wonder.cdc.gov/natality.html
- AstroDatabank: https://www.astro.com/astro-databank
- UN World Population Prospects
METHODOLOGY:
1. Download/load real birth statistics by month/day
2. Calculate planetary positions for those dates
3. Test for non-uniform distributions using chi-square tests
4. Compare real data against simulated random baseline
