Format Date

<sc-format-date> | ScFormatDate

Since 2.0

stable

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 🎉 -->
<sc-format-date date="2020-07-15T09:17:00-04:00"></sc-format-date>

import ScFormatDate from '@styledc-dev/styledc/dist/react/format-date';

const App = () => <ScFormatDate date="2020-07-15T09:17:00-04:00" />;

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 -->
<sc-format-date month="long" day="numeric" year="numeric"></sc-format-date><br />

<!-- Time -->
<sc-format-date hour="numeric" minute="numeric"></sc-format-date><br />

<!-- Weekday -->
<sc-format-date weekday="long"></sc-format-date><br />

<!-- Month -->
<sc-format-date month="long"></sc-format-date><br />

<!-- Year -->
<sc-format-date year="numeric"></sc-format-date><br />

<!-- No formatting options -->
<sc-format-date></sc-format-date>

import ScFormatDate from '@styledc-dev/styledc/dist/react/format-date';

const App = () => (
  <>
    {/* Human-readable date */}
    <ScFormatDate month="long" day="numeric" year="numeric" />
    <br />

    {/* Time */}
    <ScFormatDate hour="numeric" minute="numeric" />
    <br />

    {/* Weekday */}
    <ScFormatDate weekday="long" />
    <br />

    {/* Month */}
    <ScFormatDate month="long" />
    <br />

    {/* Year */}
    <ScFormatDate year="numeric" />
    <br />

    {/* No formatting options */}
    <ScFormatDate />
  </>
);

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.

<sc-format-date hour="numeric" minute="numeric" hour-format="12"></sc-format-date><br />
<sc-format-date hour="numeric" minute="numeric" hour-format="24"></sc-format-date>

import ScFormatDate from '@styledc-dev/styledc/dist/react/format-date';

const App = () => (
  <>
    <ScFormatDate hour="numeric" minute="numeric" hour-format="12" />
    <br />
    <ScFormatDate hour="numeric" minute="numeric" hour-format="24" />
  </>
);

Use the lang attribute to set the date/time formatting locale.
