+This demo applies different selection modes and date availability options to the Calendar component.
 
 ## Selection Modes
 
 The selected value or values are stored in the [value](/Documentation/ApiReference/UI_Components/dxCalendar/Configuration/#value) property. The following [selection modes](/Documentation/ApiReference/UI_Components/dxCalendar/Configuration/#selectionMode) are available:
 
 - *'single'*    
-A user can select only one date at a time.
+A user can select only a single date at any given time.
 
 - *'multiple'*     
-A user can select multiple dates at a time.
+A user can select multiple dates simultaneously.
 
 - *'range'*      
 A user can select a range of dates. The first and the last date in the range are stored in the [value](/Documentation/ApiReference/UI_Components/dxCalendar/Configuration/#value) property.

In this demo, these properties limit the range to three days before and after the current date. Enable the "Set minimum date" and "Set maximum date" checkboxes to apply the properties.
 
-If you need to disable specific dates, use the [disabledDates](/Documentation/ApiReference/UI_Components/dxCalendar/Configuration/#disabledDates) property. Toggle the "Disable weekends" checkbox to see how this setting affects the component's behavior.

-This demo shows how to use the [offset](/Documentation/ApiReference/UI_Components/dxScheduler/Configuration/#offset) property that specifies the minute offset within Scheduler, indicating the starting point of a day. The offset is a multiple of 5 and can range from -1440 minutes (-24 hours) to 1440 minutes (24 hours). 
+This demo uses the Scheduler component’s [offset](/Documentation/ApiReference/UI_Components/dxScheduler/Configuration/#offset) property to indicate the starting point of a day. The Scheduler’s offset can be set in multiples of 5 and can range from -1440 minutes (-24 hours) to 1440 minutes (24 hours).
 
-For instance, if you set the offset to -120, like the **First shift** in the demo, the day starts at 10:00 PM on the previous day instead of 00:00. If you set the offset to 360, like the **Second shift**, the day starts at 6:00 AM.

 ## Generate Similar Tabs Based on a Data Source       
 
-To generate similar tabs and views, bind the TabPanel to data. Use the [items](/Documentation/ApiReference/UI_Components/dxTabPanel/Configuration/items/) or [dataSource](/Documentation/ApiReference/UI_Components/dxTabPanel/Configuration/#dataSource) property to do this. Both these properties can work with local arrays, but **dataSource** also accepts a [DataSource](/Documentation/ApiReference/Data_Layer/DataSource/) object. You can use this object if you need to process the local array or fetch the array from a remote data source. In this demo, the **dataSource** property is set to a local array.
