— is seldom the hard part. 2/21/2026
This repository contains a small script, get_julian.py, which fetches
UTC time from the world‑time‑api3 service on RapidAPI and prints the
corresponding Julian Date.
I've put this on MyBinder.org: Launch link
An API key is required by RapidAPI. Place your key in settings.ini
next to the script::
API_KEY = your_rapidapi_key_here
The script will read this file at runtime; if the key is missing or the file cannot be found, it exits with an error.
