The Diary ICS plugin synchronizes your Obsidian diary entries with system calendar applications like macOS Calendar or Windows Calendar by generating an ICS subscription link. It parses diary notes based on user-configured heading levels, creating calendar events with titles, descriptions, and deep links back to the original Obsidian files. Frontmatter fields can also be included as part of the event description using custom templates. A local HTTP server hosts the ICS file, enabling real-time updates and cross-device subscriptions within the same network.

The Google Calendar Importer plugin syncs your Google Calendar events directly into your notes, allowing automatic or manual insertion of daily schedules. It can inject events into your daily note when opened or import them anywhere using a command. You can also select specific dates, and live calendar blocks render your events dynamically within markdown. It uses secure OAuth 2.0 authentication to connect with Google Calendar and respects user privacy by fetching data on demand without storing it permanently.
