+## Highlighting Specific Dates
+
+Using the `highlightedDates` property, developers can style particular dates with custom text or background colors. This property can be defined as either an array of dates and their colors, or a callback that receives an ISO string and returns the colors to use.
+
+When specifying colors, any valid CSS color format can be used. This includes hex codes, rgba, [color variables](../theming/colors), etc.
+
+To maintain a consistent user experience, the style of selected date(s) will always override custom highlights.
+
+:::note
+This property is only supported when `preferWheel="false"`, and using a `presentation` of either `"date"`, `"date-time"`, or `"time-date"`.
+:::
+
+### Using Array
+
+An array is better when the highlights apply to fixed dates, such as due dates.
+
+<HighlightedDatesArray />
+
+### Using Callback
+
+A callback is better when the highlighted dates are recurring, such as birthdays or recurring meetings.
+
+<HighlightedDatesCallback />
+
 ## Theming
 
 Ionic's powerful theming system can be used to easily change your entire app to match a certain theme. In this example, we used the [Color Creator](../theming/colors#new-color-creator) and the [Stepped Color Generator](../theming/themes#stepped-color-generator) to create a rose color palette that we can use for `ion-datetime`.
