The Habit Calendar plugin allows users to visualize their daily habits over a month using a calendar view within Obsidian. Built to work with DataviewJS, this plugin organizes habit data from Dataview tables or manually entered data into a visually appealing and interactive calendar. Users can customize habit tracking with Markdown or HTML, link habits to notes, and hover or click to preview or access related entries. This plugin is ideal for maintaining and reviewing personal productivity patterns, enabling users to track, customize, and analyze habits seamlessly within their vault.
