-You can configure what information all cards will display on their left side using the [`cardShape`](/api/config/booking-cardshape) property or the [`cardTemplate`](/api/config/booking-cardtemplate) property, which also allows customizing the appearance of each card's block.
+The left side of each card displays a fixed set of data fields. To control which fields appear or to fully replace the default layout, use one of the following properties:
+
+- [`cardShape`](/api/config/booking-cardshape) — toggle visibility of the default fields
+- [`cardTemplate`](/api/config/booking-cardtemplate) — replace the default layout with custom HTML
 
 :::info
-`cardTemplate` helps completely customize the appearance of a card by providing your own custom HTML. It gives full control over the card's layout, design and content.
-`cardShape` allows you only to modify the default template by hiding/showing fields. 
-If both are applied, `cardTemplate` will override the `cardShape` settings.
+The `cardTemplate` property fully customizes a card's appearance through custom HTML and gives full control over layout, design, and content. The `cardShape` property only hides or shows fields of the default template. If you apply both, `cardTemplate` overrides the `cardShape` settings.

-On the left side of each card the following data fields are displayed by default:
-- preview: card image
-- review: rating information with the number of rating stars (out of five) and the number of reviews
-- category: the subtitle of a card
-- title: the title of a card which is a specialist's name
-- subtitle: the subtitle of a card, for example, experience details 
-- price: the price of the service
-- details: other details of a card

+## Convert UTC data to the local timezone
+
+The widget operates in the local timezone. If the server returns UTC timestamps, convert each timestamp before passing it into the widget, and convert it back to UTC before posting reservations.
 
-The widget applies a local timezone but if you have UTC data it's necessary to convert data to a local timezone.
+The helpers below handle both directions:
 
-For example, if you have UTC timestamps, you can apply the functions provided in the example below to convert them. The **g2l** function converts a UTC timestamp into the local timezone. During the data loading process, this function is used to convert the times in *usedSlots* and *slots* from UTC to the local time. The **l2g** function converts a local time back to UTC. It's applied during slots reservation, namely, the **l2g** function is used to convert the local time (from slot.time[0]) to UTC before sending it to the server.
+- `g2l` — convert a UTC timestamp to the local timezone (apply on incoming `usedSlots` and `slots.dates`)
+- `l2g` — convert a local timestamp back to UTC (apply on `slot.time[0]` before sending to the server)
