Calendar

<sl-calendar> | SlCalendar
Since 2.0 experimental

A calendar prototype for Shoelace.

<sl-calendar></sl-calendar>

Examples

Month & Day Labels

Month and day labels can be customized using the month-labels and day-labels attributes. Note that month names are localized automatically based on the component’s lang attribute, falling back to the document language. 

<sl-calendar month-labels="short" day-labels="narrow"></sl-calendar>

Showing Adjacent Dates

By default, only dates in the target month are shown. You can fill the grid with adjacent dates using the show-adjacent-dates attribute. 

<sl-calendar show-adjacent-dates></sl-calendar>

Date Selection

One or more dates can be selected by setting the selectedDates property. An array of dates is accepted and the selection does not have to be continuous. 

<sl-calendar class="calendar-selection"></sl-calendar>

<script>
  const calendar = document.querySelector('.calendar-selection');
  const today = new Date();

  // Set the selected date range from the 12-15 of the current month
  calendar.selectedDates = [
    new Date(today.getFullYear(), today.getMonth(), 12),
    new Date(today.getFullYear(), today.getMonth(), 13),
    new Date(today.getFullYear(), today.getMonth(), 14),
    new Date(today.getFullYear(), today.getMonth(), 15)
  ];
</script>

With Borders

To add a border, set the --border-width custom property. You can further customize the border with --border-color and --border-radius. 

<sl-calendar style="--border-width: 1px;"></sl-calendar>

Localizing the Calendar

By default, the calendar will use the document’s locale. You can use the lang attribute to change this. 

<sl-calendar lang="es"></sl-calendar>
