Format Date
<sl-format-date> | SlFormatDate
Formats a date/time using the specified locale and options.
Localization is handled by the browser’s
Intl.DateTimeFormat
API. No language packs are required.
<!-- Shoelace 2 release date 🎉 --> <sl-format-date date="2020-07-15T09:17:00-04:00"></sl-format-date>
The date
attribute determines the date/time to use when formatting. It must be a string that
Date.parse()
can interpret or a
Date
object set via JavaScript. If omitted, the current date/time will be assumed.
When using strings, avoid ambiguous dates such as 03/04/2020
which can be interpreted as
March 4 or April 3 depending on the user’s browser and locale. Instead, always use a valid
ISO 8601 date time string
to ensure the date will be parsed properly by all clients.
Examples
Date & Time Formatting
Formatting options are based on those found in the
Intl.DateTimeFormat
API. When formatting options are provided, the date/time will be formatted according to those values. When no
formatting options are provided, a localized, numeric date will be displayed instead.
<!-- Human-readable date --> <sl-format-date month="long" day="numeric" year="numeric"></sl-format-date><br /> <!-- Time --> <sl-format-date hour="numeric" minute="numeric"></sl-format-date><br /> <!-- Weekday --> <sl-format-date weekday="long"></sl-format-date><br /> <!-- Month --> <sl-format-date month="long"></sl-format-date><br /> <!-- Year --> <sl-format-date year="numeric"></sl-format-date><br /> <!-- No formatting options --> <sl-format-date></sl-format-date>
Hour Formatting
By default, the browser will determine whether to use 12-hour or 24-hour time. To force one or the other,
set the hour-format
attribute to 12
or 24
.
<sl-format-date hour="numeric" minute="numeric" hour-format="12"></sl-format-date><br /> <sl-format-date hour="numeric" minute="numeric" hour-format="24"></sl-format-date>
Localization
Use the lang
attribute to set the date/time formatting locale.

English: <sl-format-date lang="en"></sl-format-date><br /> French: <sl-format-date lang="fr"></sl-format-date><br /> Russian: <sl-format-date lang="ru"></sl-format-date>

The date/time to format. If not set, the current date and time will be used. When passing a string,
it’s strongly recommended to use the ISO 8601 format to ensure timezones are handled correctly. To
