Here are two ways to turn this exact information into a color-coded PDF calendar:
Method 1: Export Directly from Safari on iPhone (No Coding Needed)
 * Open Safari on your iPhone and visit htmlrunner.com (or any free online HTML viewer).
 * Copy the HTML block below and paste it into the viewer editor.
 * Tap Share (the box with an upward arrow) at the bottom of Safari.
 * Select Print.
 * On the print preview screen, pinch outwards with two fingers on the page image to expand it into a full-screen PDF view.
 * Tap the Share button at the top right to save the generated color-coded PDF directly to your Files app or send it via email.
Method 2: Generate PDF via Python (reportlab)
If you want to generate a crisp, vector-formatted PDF file automatically, run this Python script using reportlab:
from reportlab.lib import colors
from reportlab.lib.pagesizes import letter
from reportlab.lib.styles import getSampleStyleSheet, ParagraphStyle
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer, Table, TableStyle, HRFlowable
