The sbb-calendar component displays a calendar that allows the user to select a date. For accessibility purposes it's rendered as a native table element and each day is a button.
While being deeply linked to the implementation of the sbb-datepicker-toggle component, it can be used on its own.
For date inputs (min, max, selected-date) the accepted formats are:
- Date objects
- ISO String
- Unix Timestamp (number of seconds since 1 Jan 1970)
and it's recommended to set the time to 00:00:00.
The component displays one month by default; two months can be displayed setting the wide property to true. It's also
possible to filter out unwanted date using the dateFilter function property.
Consumers can listen to the dateSelected event on the sbb-calendar component to intercept the selected date
which can be read from event.detail.
Note that using the dateFilter function as a replacement for the min and max properties will most likely result in a significant loss of performance.

Usage
Calendar with selected date and bounds:
<sbb-calendar
min="1600000000"
max="1700000000"
selected-date="1650000000"
></sbb-calendar>Testing
To specify a specific date for the current datetime, you can use the data-now attribute (timestamp in milliseconds).
This is helpful if you need a specific state of the component.
