Date & Time based Predicate Reference
This page describes and gives examples for all the date and time based predicates you can use when creating queries with the prismic.io Ruby development kit.
All of these predicates will work when used with either the Date or Timestamp fields, as well as the first and last publication dates.
Note that when using any of these predicates with either a Date or Timestamp field, you will limit the results of the query to the specified custom type.
The date_after predicate checks that the value in the path is after the date value passed into the predicate.
This will not include anything with a date equal to the input value.

Prismic::Predicates.date_after("my.article.release-date", "2017-01-23")The date_before predicate checks that the value in the path is before the date value passed into the predicate.
