FlexiCal

FlexiCal is a flexible calendar plugin for Obsidian that surfaces the notes you care about in a calendar view. You define one or more calendars, each with its own filter and color, and FlexiCal marks the days that have matching notes.

What it does

• Adds a calendar to the right sidebar (open it with the Show calendar ribbon icon).
• For every calendar you configure, FlexiCal scans your vault for notes whose frontmatter date falls in the month being viewed and that match the calendar's filter.
• Matching notes are shown as small colored dots on their day, using each calendar's color. Days with matches from multiple calendars show a dot per calendar, up to six dots per day.
• A note belongs to only one calendar: the first calendar (in the order listed in settings) whose filter and date field it matches. Reorder calendars to change which one claims a shared note.
• Click a day to open its notes. If a single note matches, it opens directly; if several match, a picker lets you choose.
• The view updates automatically as notes are created, modified, or deleted.

Configuration

Calendars

This is the heart of FlexiCal. Use the + button next to the Calendars heading to add a calendar, and the trash icon on a calendar to remove it. The order calendars appear in matters: a note is claimed by the first calendar it matches, so list more specific calendars above more general ones. Each calendar has the following settings:

• Name — A label for the calendar. Used only to identify it in settings.

• Color — The color of the dots drawn for this calendar's matching notes.

• Date field — The frontmatter property that holds a note's date (for example, date). A note is placed on the day given by this field. Values may be a plain date (2026-06-14) or a full timestamp; dates are interpreted in UTC.

• Week field — Optional. The frontmatter property that holds a note's ISO week (for example, 2026-W33), for weekly notes. When a note has no value for the date field, FlexiCal falls back to this field and places the note on the Monday of that week.

• Filter — Optional. Restricts which notes this calendar includes. Click Edit filter to open the filter builder. Filters can be combined and nested:

  • All of the following… — matches a note only if every child filter matches (AND).
  • Any of the following… — matches if at least one child filter matches (OR).
  • None of the following… — matches only if no child filter matches (NOT).
  • Frontmatter property… — matches on a frontmatter property by type (text, number, date, checkbox, list, or tag), each with type-appropriate operators (such as contains, equals, greater/less than, or regex).
  • File path… — matches notes whose path fits a glob pattern (for example, journal/*.md).

  With no filter, a calendar includes every note that has a value for its date (or week) field and hasn't already been claimed by an earlier calendar.
