PDF Calendar Parsing with PyMuPDF

Installation

pip install pymupdf

Approach

Use page.get_drawings() to extract all drawn shapes.
Identify the 15-min grid: horizontal lines with width > 100 and height < 3. Sort by y-position. The first line is time 0 (12:00 AM), each subsequent line is +15 min.
Identify event blocks: filled rectangles with height > 5 and width > 100.
Map each block's top/bottom y to the nearest grid line: slot = round((y - grid[0]) / spacing), time = slot * 15 minutes from midnight.
Blue blocks: check if fill[2] > 0.6 and fill[0] < 0.55 (blue-dominant). These are low-priority and overwritable.

Grid line to time mapping

lines = sorted([d["rect"].y0 for d in drawings if d["rect"].width > 100 and d["rect"].height < 3])
spacing = lines[1] - lines[0]  # ~7.5 px

def y_to_slot(y):
    return round((y - lines[0]) / spacing)

def slot_to_time(slot):
    total_min = slot * 15
    h, m = divmod(total_min, 60)
    return h, m  # 24-hour format

Block padding

Blocks have ~1px padding on each side, so round() to nearest slot gives correct results. Always verify by checking that durations are multiples of 15 minutes.

Identifying block colors

Gray (out of office): fill ≈ (0.38, 0.38, 0.38)
Red/Pink (meetings): fill ≈ (0.90, 0.49, 0.45)
Blue (low-priority): fill ≈ (0.47, 0.53, 0.80) — OVERWRITABLE
Yellow/Green (labels): fill ≈ (0.75, 0.79, 0.20) — these are small label squares inside blocks, ignore
