# Date Utilities

This group of utilities helps you work with dates by performing calculations, formatting, and managing time zones. Below are the available actions:

1. **Find difference between dates:**

   Calculate the difference between two dates (start and end) in your chosen unit, such as years, months, days, etc.
2. **Add/Subtract dates:**

   Perform calculations to add or subtract a specific number of units (like days, months, or years) to a given date and get the result.
3. **Format Date:**

   Convert programmatic dates (e.g., timestamps from a database) into a human-readable format. You can customize the format to match your design requirements.
4. **Apply Timezone to Date:**

   Convert a given date or timestamp into a different timezone based on your selection.

In the next section, we’ll explore how to configure each of these actions in detail.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fireapis.com/the-basics/logics/actions/date-utilities.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
