# Date and time attributes

The date and time [attribute type](https://doc.ibexa.co/en/latest/product_catalog/products/#product-attributes) allows you to represent date and time values as part of the product specification in the [product catalog](https://doc.ibexa.co/en/latest/product_catalog/product_catalog_guide/index.md).

You can use it to store, for example, manufacturing dates, expiration dates, or event dates, all with specified accuracy.

## Usage

You can manage the date and time attribute type through the back office, [data migrations](https://doc.ibexa.co/en/latest/content_management/data_migration/importing_data/#date-and-time-attributes), REST, or through the PHP API. It also supports [searching](https://doc.ibexa.co/en/latest/search/criteria_reference/product_search_criteria/index.md) by using [DateTimeAttribute](https://doc.ibexa.co/en/latest/search/criteria_reference/datetimeattribute_criterion/index.md) and [DateTimeAttributeRange](https://doc.ibexa.co/en/latest/search/criteria_reference/datetimeattributerange_criterion/index.md) criteria.

When creating an attribute based on the date and time attribute type you can select the accuracy level to match your needs:
