The OZ Calendar plugin is a game-changer for Obsidian users who want to visualize their notes on a calendar. With this plugin, you can easily view your notes by date using any YAML key or file name with a custom date value. The plugin offers two configuration options: YAML and File Name. In the YAML option, you define the key and date format used in your YAML files. For the File Name option, you adjust the default date format to match the naming convention of your files. This plugin also allows you to create new notes with a single click from the calendar view or using keyboard shortcuts. With its intuitive design and customizable settings, the OZ Calendar plugin is an excellent tool for organizing and navigating your Obsidian notes.
