Life in Weeks (by Months)

A minimalist, printable visualizer of a human lifespan broken down by months and weeks — inspired by the idea of measuring life visually.

Overview

This web application allows you to:

• Input a date of birth and a current date.
• Generate a life calendar showing 90 years, each split into 12 months and 4 weeks per month.
• Visually track time passed by highlighting filled cells from birth to the selected current date.

Useful for personal reflection, habit tracking, or as a printable life calendar.

Features

• Simple, responsive design.
• No dependencies — pure HTML, CSS, and JavaScript.
• Printable layout with non-essential elements hidden on print.
• Color-coded cells to show elapsed time.

Usage

1. Open the HTML file in a browser.
2. Enter your birth date.
3. Optionally adjust the current date (defaults to today).
4. Click Generate Table.
5. The table will display 90 years, each with 48 weeks (4 weeks per month), and highlight the elapsed time.

Notes

• Each cell represents approximately one week.
• Months are simplified to always show 4 weeks for visual clarity.
• To print, use your browser’s print feature — interface elements are hidden automatically.
