**Daily Notes** is a core [[Plug-in (computing)|plugin]] included with [[Obsidian (software)|Obsidian]], a [[Personal knowledge management|personal knowledge management]] and [[Note-taking|note-taking]] application. The plugin allows users to automatically create and open a new note for each day, serving as a built-in journaling and daily logging feature. Daily Notes is one of Obsidian's most widely used core plugins and forms a foundational element of many users' [[Personal knowledge management|knowledge management]] workflows. When activated, the plugin adds a button to the Obsidian interface that creates or opens a note named with the current date. Users can configure the date format, specify a default folder for daily notes, and designate a [[Template (file format)|template]] file that pre-populates each new note with a consistent structure. This templating capability integrates with other Obsidian plugins such as **Templater** and the core **Templates** plugin, enabling dynamic content insertion including timestamps, task lists, and links to related notes. Daily notes can function as an entry point into a user's [[Zettelkasten|Zettelkasten]] or other knowledge system, providing a chronological index that connects to project notes, meeting records, and ongoing tasks through Obsidian's [[Bidirectional linking|bidirectional linking]] system. The plugin's functionality has been extended by community plugins such as **Periodic Notes**, which generalizes the concept to weekly, monthly, quarterly, and yearly notes, and **Calendar**, which provides a visual calendar interface for navigating daily notes. Daily Notes remains a core plugin shipped with Obsidian by default, though like all core plugins it can be disabled in the application's settings.
