On This Day in History (Obsidian Plugin)

Insert Wikipedia’s “On this day” for today directly into your current Obsidian note — cleanly formatted as Markdown.

The plugin fetches the current day’s Wikipedia page (e.g. January 3), extracts the Events, Births, and Deaths sections, and inserts them at your cursor position.

Settings

Timezone

By default, the plugin uses your system timezone (Auto) to determine what “today” means.

If you travel, or if you for any other reason want more control, you can switch to Manual timezone mode:

• Auto (default)
  Uses your system’s current timezone.

• Manual Lets you choose a specific timezone. When switching to Manual, the system-detected timezone is preselected for convenience.

Link Display

Control how Wikipedia links appear in the inserted content:

• Inline (default) Links appear naturally within the text, preserving the original Wikipedia formatting.

• Grouped Link text appears in the content without hyperlinks, and all links are collected under a "Links" section at the end of each subsection (Events, Births, Deaths).

• None All links are removed, leaving only plain text.

You can find these settings under:

Settings → On This Day in History
