 ### Added
 - [#932](https://github.com/plotly/dash-core-components/pull/932). Adds a new copy to clipboard component.
+- [#948](https://github.com/plotly/dash-core-components/pull/948)] Adds `disabled_days` prop to `DatePickerRange` and `DatePickerSingle` components. With this prop you can specify days that should be made unselectable in the date picker, in addition to those that fall outside of the range specified by `min_date_allowed` and `max_date_allowed`.
