# Custom Date & Time Format Strings

## Overview

DateTime objects within Decisions can be formatted as a string using the [Parse Date With Format](https://documentation.decisions.com/step-library/docs/parse-date-with-format-step) and [Get Formatted Date](https://documentation.decisions.com/step-library/docs/en/get-formatted-date-step) steps.

The following table provides example formats and the expected output for a date when used with the above steps.

Some of the examples contain strings with characters reserved for formatting, such as the 'M' in GMT. These strings will need to be encapsulated with double/single quotes.  
  
For more information, please visit the following article [Custom Date and Time Format Strings](https://docs.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings).
