format_datetime

The format_datetime filter formats a date time:

public function formatDateTime(Environment $env, $date, ?string $dateFormat = ‘medium’, ?string $timeFormat = ‘medium’, string $pattern = ‘’, $timezone = null, string $calendar = ‘gregorian’, string $locale = null): string

{# Aug 7, 2019, 11:39:12 PM #}
{{ '2019-08-07 23:39:12'|format_datetime() }}

You can tweak the output for the date part and the time part:

{# 23:39 #}
{{ '2019-08-07 23:39:12'|format_datetime('none', 'short', locale='fr') }}

{# 07/08/2019 #}
{{ '2019-08-07 23:39:12'|format_datetime('short', 'none', locale='fr') }}

{# mercredi 7 août 2019 23:39:12 UTC #}
{{ '2019-08-07 23:39:12'|format_datetime('full', 'full', locale='fr') }}

Supported values are: none, short, medium, long, and full.

For greater flexiblity, you can even define your own pattern (see the ICU user guide for supported patterns).

{# 11 oclock PM, GMT #}
{{ '2019-08-07 23:39:12'|format_datetime(pattern="hh 'oclock' a, zzzz") }}

By default, the filter uses the current locale. You can pass it explicitly:

{# 7 août 2019 23:39:12 #}
{{ '2019-08-07 23:39:12'|format_datetime(locale='fr') }}
