Extract calendar events, blocks, and time slots from PDF calendar files using pdfplumber.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PDF Calendar Parsing Skill
## Overview
This skill covers extracting calendar events and time blocks from PDF calendar documents using `pdfplumber`, a Python library for extracting text and tables from PDF files.
## Installation
```bash
pip install pdfplumber
```
## Key Concepts
### How pdfplumber Works
- Opens PDF files and extracts text with position information
- Can identify text bounding boxes (x0, y0, x1, y1 coordinates)
- Supports extracting tables and structured data
### Calendar Grid Extraction
For a calendar with hourly/time-based layout:
1. Extract all text from the PDF with position data
2. Identify time labels (hours on the left axis)
3. Identify event blocks by text content and bounding boxes
4. Calculate event duration by comparing Y-coordinates
## Code Examples
### Basic PDF Opening
```python
import pdfplumber
with pdfplumber.open('/root/calendar.pdf') as pdf:
page = pdf.pages[0]
text = page.extract_text()
print(text)
```
### Extracting Text with Positions
```python
import pdfplumber
with pdfplumber.open('/root/calendar.pdf') as pdf:
page = pdf.pages[0]
# Get all text objects with their positions
for char in page.chars:
…Read the whole file at its exact version.
How to install
mdr add cxcscmu/skilllearnbench/pdf-calendar-parsing@sha256:9759125e1bd8d3fcThe line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
