Daily-note plugins: Calendar and Periodic Notes

For this example, we manually placed official release files in an isolated, author-created Vault, then enabled and operated the plugins through the GUI. We did not test installation through Community plugins → Browse → Install.

1. In your practice Vault, create empty folders named 日誌, 週誌, and テンプレート. This example uses the Markdown provided below.
2. The files used in this example are available in the official Calendar 1.5.10 release and the official Periodic Notes 0.0.17 release. The manual file layout is shown below.
3. Turn on Daily notes in Settings → Core plugins. In this test, Command palette was also on, and we confirmed that Quick switcher was on.
4. After confirming trust for the Vault you prepared yourself, enable Periodic Notes and Calendar in Settings → Community plugins. The original screenshot below shows both plugins enabled.
5. Open the right sidebar and select the Calendar tab. If another tab, such as Backlinks, remains selected, the calendar will not be visible.

  styles.css

In this Calendar release, styles are included in main.js; we did not download a separate styles.css. The layout above shows the actual files used. The plugins themselves are not included in this page’s downloadable ZIP.

Save the daily template to テンプレート/日.md. The date variable used here is native to Obsidian.

# {{date:YYYY-MM-DD}}

1. Select 2026-9-30 in Calendar. In this test, the confirmation appeared in a separate Settings window that was already open.
2. Check the target date 2026-09-30 in New Daily Note, then select Create in that window. 日誌/2026-09-30.md opened in the main editor.
3. After the heading was replaced with 2026-09-30, we added a confirmation line to the content and saved with Ctrl+S.
4. We selected the index to move to another note, then selected 日誌/2026-09-30.md once from the file list on the left. After reopening, its content still matched the saved 235 bytes.

Save the weekly template to テンプレート/週.md. Its content is a static, author-written template. We do not present this as a test of arbitrary weekly-variable substitution.

1. Select 40 in Calendar with the week-number column visible. In this environment, the target was named 2026-W40.
2. In the separate Settings window, check 2026-W40 under New Weekly Note, then select the actual Create button.
3. We added a confirmation line to the content opened at 週誌/2026-W40.md and saved with Ctrl+S. The result is the original static weekly template plus that line.
4. We moved to the index, then selected 週誌/2026-W40.md once from the file list on the left. After reopening, its content still matched the saved 219 bytes.

Previous-month navigation and return to the current month

In a separate fixed trial, we selected Previous Month once in Calendar to move from Sep 2026 to Aug 2026, then selected Next Month once to return to Sep 2026. We did not test every month or year boundary.

The 3 input files—the index and templates—are separate from the 2 examples saved through the GUI. Plugin files and settings JSON are not included. The inputs are intended for your practice Vault to avoid overwriting existing notes. Importing them into a reader’s Vault has not been tested.

• Official Obsidian 1.13.7 for Linux, Installer 1.13.7, and the English UI. Actual version displays for Calendar 1.5.10 and Periodic Notes 0.0.17.
• Actual GUI settings in an author-created Vault; one daily note and one weekly note, covering creation confirmation, content, saving, and reopening in the same app. Month navigation was checked in a separate fixed trial.
• Official plugin release assets were placed manually. Helper code prepared the initial environment, read state and saved files, and copied originals. API calls did not replace creating, editing, saving, or reopening notes.
• The published PNG and Markdown files retain their original bytes. iOS, other operating systems, SimpleMemo, Sync, every date/week/month/time/time zone, and effects on productivity or traffic were not tested.

We retained the original failed attempts: startup stopping during preparation, mismatched beta-version screens and saved settings, clicking a hidden tab, and missing confirmation in another window. This article’s creation and saving examples come from a separate fixed trial. Ctrl+O did not produce an observable Quick switcher screen; reopening was first confirmed by an actual click in the file list for the same destination. The details and original-file mapping are documented in the test record.

Actual General version screen

• Calendar 1.5.10: official README at the pinned commit
• Calendar settings source at the pinned revision
• Periodic Notes 0.0.17: official README at the pinned commit
• Periodic Notes settings UI source at the pinned revision

We checked the original files, settings, and actual-operation records separately. We did not verify a reproducible build matching the official release files to the source.

Once you can open notes by date and week number, choose where to capture short notes during the day. The main guide covers appending from iPhone to a Obsidian daily note, the built-in daily-note feature, and date formats.
