Why Airtable Calendar Shows "Checked" Instead of a Tick Symbol

You added a checkbox field to your calendar event display, expecting to see a small tick symbol next to events where the box is checked. Instead, you see the word "Checked" in plain text. Unchecked records show nothing, and checked records show "Checked".

This is how Airtable handles checkbox fields in calendar view: it renders the text value of the field rather than a visual checkbox element. The graphical tick you see in the grid view is a UI element that the calendar does not replicate.

Why This Happens

In the grid view, Airtable renders checkbox fields as interactive UI elements with visual states. In the calendar view, each event displays field values as text strings. A checked checkbox has a text value of "Checked" and an unchecked one has an empty string. The calendar shows those text values directly.

This is consistent across other view types that show abbreviated event data: gallery view, timeline view, and calendar view all represent checkbox fields as their text equivalent rather than visual checkboxes.

The Workaround: Use a Formula Field With an Emoji

Add a formula field that returns a visual symbol based on the checkbox state. The formula converts the boolean checkbox value into an emoji:

IF({Your Checkbox Field}, "✅", "")

Or for a simpler tick mark:

IF({Your Checkbox Field}, "✓", "")

When checked, the formula returns the emoji or tick character. When unchecked, it returns nothing. The calendar displays this formula field as its text value, which is now a visual symbol rather than the word "Checked".

Add this formula field to the calendar event's displayed fields in the calendar settings. Remove the original checkbox field from the display, or keep both if you want the visual symbol and the word alongside each other.

Setting Up the Calendar Display Fields

To control which fields appear on calendar events:

  1. Open the calendar view in your base
  2. Click the calendar settings panel (click in an empty area of the calendar to open it)
  3. Find the Fields or Event display section
  4. Add your formula field to the display list
  5. Remove the original checkbox field if you no longer want to see "Checked"

The calendar events now show the emoji tick for any event where the checkbox is checked.

Other Field Types That Have This Issue

The same text-rendering behaviour applies to other visual field types in calendar view:

  • Rating fields show a number rather than stars
  • Progress fields show a percentage rather than a bar
  • Duration fields show the number in seconds rather than a formatted duration

In each case, the same workaround applies: add a formula field that formats the value the way you want to see it, and display that formula field on the calendar instead.
