Shopify » Date

A Shopify Date works similar to the ACF type Date but always stores the date in ISO 8601 format (YYYY-MM-DD) without a presumed timezone. A field of type Shopify » Date can be subject to date filters in Liquid:

{{ product.metafields.accentuate.published_date.value | date: "%a, %b %d, %y" }}
