Changeset 35517 for trunk/src/wp-includes/functions.php

Timestamp:

Message:

Introduce wp_maybe_decline_date() for languages where certain date formats need to be declined, and hook it to the date_i18n filter.

If the locale specifies that month names require a genitive case in certain formats like 'j F Y' or 'j. F', the month name will be replaced with a correct form.

Fixes #11226.
