# Initialize Date Field

Initialize Date and Date-Time fields

## Overview

In this example, the rule run on the load of a step and initializes both a date only field and a date+time field to the present date/time.

## Rule Logic

The below logic gets the current date and builds date and date-time values appropriate to initialize the fields.  The fields are only initialized if they do not already have a value set.

```
// Initialize a date and date/time to today and now respectively

// get today's date
const now = new Date();
const today = `${now.getFullYear()}-${(now.getMonth() + 1).toString().padStart(2, '0')}-${now.getDate().toString().padStart(2, '0')}`;

const nowInUtc = `${now.getUTCFullYear()}-${(now.getUTCMonth() + 1).toString().padStart(2, '0')}-${now.getUTCDate().toString().padStart(2, '0')}` + 
`T${now.getUTCHours().toString().padStart(2, '0')}:${now.getUTCMinutes().toString().padStart(2, '0')}:${now.getUTCSeconds().toString().padStart(2, '0')}Z`;

// only initialize the response date if not already set
if (!ResponseDate.value)
  ResponseDate.value = today;

// only initialize the event date and time if not already set - set it in UTC
if (!EventDateTime.value)
  EventDateTime.value = nowInUtc;
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.feathery.io/platform/build-forms/advanced-logic/examples/initialize-date-field.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
