Bullet Journal Creator

A small Python tool that generates a printable yearly bullet journal as a PDF. It creates a front page, monthly overview and notes pages, weekly planning pages, and then merges everything into one bullet_journal.pdf file.

Technologies

• Python
• ReportLab
• pypdf
• Pillow
• python-dateutil

Features

• Generates a complete journal for a selected year
• Includes monthly and weekly calendar pages
• Supports English and German labels
• Adds configurable birthdays, holidays, anniversaries, and icons
• Exports the journal as an A4 PDF

Installation

Clone or download the project, open a terminal in the project folder, and create a virtual environment:

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

On Windows, activate the environment with:

.venv\Scripts\activate

Create the Bullet Journal

Run the script from the project root:

python3 main.py

This creates a bullet journal for the default year 2026.

To generate a journal for another year, pass the year as an argument:

python3 main.py 2027

The generated file is saved as:

bullet_journal.pdf

Intermediate monthly and weekly PDF files are stored in the folders inlay_month, inlay_week, and inlay_front.

Customization

Open constants.py to adjust the journal content.

Change the language:

LANG = "en"  # English
LANG = "de"  # German

Add personal dates to IMPORTANT_DATES:

[01, 01, "Birthday", "cake.png", 2000, ["week", "month"]]

The values represent:

[day, month, label, icon, reference year, visible views]

Available icons are stored in the icons folder. An empty icon value displays the event as plain text.
