Entity Options

Name	Type	Description
icon	string	null Add an icon to a calendar. If not set, will use the entity icon set in HA. see note below
startTimeFilter	string	Only shows events between specific times _NOTE_ must be set with endTimeFilter format: '10:00'
endTimeFilter	string	Only shows events between specific times _NOTE_ must be set with startTimeFilter format: '17:00'
maxDaysToShow	integer	7 Maximum number of days to show. Overrides main configuration maxDaysToShow for this calendar
blocklist	string	null Case-insensitive regex to ignore events whose title matches. Matched against the original summary, even when titleReplace rewrites the display title
blocklistLocation	string	null Case-insensitive regex to ignore events whose location matches
allowlist	string	null Case-insensitive regex to only show events whose title matches. Matched against the original summary
allowlistLocation	string	null Case-insensitive regex to only show events whose location matches
showMultiDay	boolean	false Split multi-day events across all days
name	string	null Add a calendar name to be shown with event
eventTitle	string	Where no event title exists, add this string instead. Only applies to this entity; can also be set globally
color	string	null Default color for this calendar’s event titles
showDescription	boolean	Per-entity override of the global showDescription. Useful to show descriptions for some calendars (e.g. kids) and hide them for others
showHours	boolean	Per-entity override of the global showHours. Useful for public iCal feeds (e.g. holidays) where times are not meaningful
fontSize	string|number	Font size of this calendar’s event titles. Numbers are treated as px; strings pass through ('120%', '1.1em')
fontWeight	string|number	Font weight of this calendar’s event titles. Accepts CSS keywords ('bold') or numeric weights (700)
titleReplace	list	Ordered list of {from, to} rewrites applied to the display title. from is a case-insensitive regex; to is the replacement (empty strips the match). See example below

Note

It is not advised to use allowlist & blocklist under the same entity.

Example — rewrite shared-calendar titles

Strip a ``Dinner = `` prefix so a filtered “Dinners” card shows only the meal:

type: custom:atomic-calendar-revive
entities:
  - entity: calendar.family
    allowlist: '^Dinner = '
    titleReplace:
      - from: '^Dinner = '
        to: ''

Rename per-person tags (“Daddy Work” → “Work”, strip “hat Geburtstag”):

entities:
  - entity: calendar.daddy
    name: Daddy
    titleReplace:
      - from: '^Daddy '
        to: ''
      - from: ' hat Geburtstag$'
        to: ''

Note

Set the calendar entity icon by going to Settings -> Entities search for calendar Click the calendar you wish to change, click the cog in the top right and set a new icon.

This is how I recommend setting up the icons now.
