date_i18n( string $format, int|bool $timestamp_with_offset = false, bool $gmt = false ): string

Retrieves the date in localized format, based on a sum of Unix timestamp and timezone offset in seconds.


If the locale specifies the locale month and weekday, then the locale will take over the format for the date. If it isn’t, then the date format string will be used instead.

Note that due to the way WP typically generates a sum of timestamp and offset with strtotime(), it implies offset added at a current time, not at the time the timestamp represents. Storing such timestamps or calculating them differently will lead to invalid output.


Format to display the date.
A sum of Unix timestamp and timezone offset in seconds.


Whether to use GMT timezone. Only applies if timestamp is not provided.



string The date, translated if locale specifies it.


function date_i18n( $format, $timestamp_with_offset = false, $gmt = false ) {
	$timestamp = $timestamp_with_offset;

	// If timestamp is omitted it should be current time (summed with offset, unless `$gmt` is true).
	if ( ! is_numeric( $timestamp ) ) {
		// phpcs:ignore WordPress.DateTime.CurrentTimeTimestamp.Requested
		$timestamp = current_time( 'timestamp', $gmt );

	 * This is a legacy implementation quirk that the returned timestamp is also with offset.
	 * Ideally this function should never be used to produce a timestamp.
	if ( 'U' === $format ) {

		$date = wp_date( $format, null, new DateTimeZone( 'UTC' ) );
	} elseif ( false === $timestamp_with_offset ) { // Current time in site's timezone.
		$date = wp_date( $format );
	} else {
		 * Timestamp with offset is typically produced by a UTC `strtotime()` call on an input without timezone.
		 * This is the best attempt to reverse that operation into a local time to use.

User Contributed Notes

  1. Skip to note 9 content

    The date_i18n() function basically behaves exactly like the normal PHP date() function, except that it also translates things like month names and weekdays and similar into the current locale for the site. You can replace a call to date() with a call to date_i18n(), using the same arguments that date() normally takes.

    The date_i18n() function also takes an additional argument, which should be used only if you’re specifying GMT (UTC) time and not a local time.

    The core of WordPress includes the necessary pieces to translate months and days and so forth in the core code, so this function is one translation function which does not need a text-domain when used in plugins and themes. The translations will always be included in the core language packs.

    Note that the “format”, however, is not converted to a local one if you manually specify it. If you need a localized format, then you should use get_option('date_format') if you need the format set by the user in Settings->General, and thus one of their choosing. Alternatively, you can wrap your predefined format in __() in order to allow translators to adjust the date to the proper local format. If you do so, then you should also include a translator comment, to let the translators know what the date format is referring to and where it is used, so they can convert it accurately.

    It is important to note that date_i18n():

    1. does not have full feature parity with date(), not all formats are supported (such as shorthands);
    2. does not accept Unix timestamp (despite documented to), the expected value is “WordPress timestamp” (offset by time zone);
    3. has issues with certain timezone settings, such as numerical ones;
    4. does nothing with $gmt argument under normal circumstances;

    Any use of this function must be carefully audited for correctness, especially in regards to output of time zones.

  3. Skip to note 12 content
    $dt_gmt = '2018-12-03 00:00:00';
    echo 'date_i18n GMT, gmt=false: ' . date_i18n($settings_datetime_format, strtotime($dt_gmt)) . '<br>';
    echo 'date_i18n GMT, gmt=true: ' . date_i18n($settings_datetime_format, strtotime($dt_gmt), true) . '<br>';


    date_i18n GMT, gmt=false: December 3, 2018 12:00 am
    date_i18n GMT, gmt=true: December 3, 2018 12:00 am

    The third argument has no effect if second argument was set.

    To display translated date/time based on WP settings (time zone, format). The $unixtimestamp argument must be convert from GMT like this.

    $dt_gmt = '2018-12-03 00:00:00';
    $dt = get_date_from_gmt($dt_gmt, 'Y-m-d H:i:s');// convert from GMT to local date/time based on WordPress time zone setting.
    echo date_i18n(get_option('date_format') . ' ' . get_option('time_format') . ' (P)', strtotime($dt));// get format from WordPress settings.

    The result will be:

    ธันวาคม 3, 2018 7:00 am (+07:00)

    This is based on Thai language, Bangkok time zone.

    To get both the date and time within a single string, use date_i18n twice with a separator. At the same time, you can also retrieve the local Date and Time formats that are set within the General Settings page.

    For example, to return: ‘March 3, 2018 @ 7:18 am’ (formatted for the US, Eastern Standard Time in the General Settings page):

    $datetime = date_i18n(get_option('date_format'), current_time('timestamp')) .' @ '. date_i18n(get_option('time_format'), current_time('timestamp'));

    A simple way to show the default format of your install date/time; and to see if it works well with i18n formatting is to pull both date and time using PHP:

    $format      = get_option('date_format') . ' ' . get_option('time_format');
    $check_stamp = date_i18n($format, current_time('timestamp'));

    Display by echoing esc_html($check_stamp);

    Result: February 25, 2022 11:36 pm

    If it shows incorrectly then you can go to your Setting > General to make good.

    Convert another UTC time to your own timezone.
    Let us suppose you are in UTC+10 timezone And want to convert another timezone to your timezone. You can do this by adding +10 on date_18n() function.

    $converted_date = date_i18n( get_option( 'date_format' ), strtotime( '2019-06-07 00:35:32' . '+11' ) )
