# Find Difference Between Dates

This action allows you to calculate the time difference between two dates based on the unit of measurement you choose. Below are the configuration options:

#### Pick Start Date

Use the **Dynamic Data Source Selector** popup to select or enter the start date from a previous action or the provided payload.

#### Pick End Date

Similarly, use the **Dynamic Data Source Selector** popup to select or enter the end date from a previous action or the provided payload.

#### Select Unit of Measurement

Choose the unit for the difference calculation, such as years, months, days, hours, minutes, or seconds. The result will be displayed based on this selection.

We’ve included screenshots to demonstrate how to configure this action and the corresponding results. Below is the sample payload data used for this logic:

```json
{
  "start_date": "2024-02-03",
  "end_date": "2025-02-03"
}
```

## 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/find-difference-between-dates.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.
