# DateFeatures

A set of date and time features.

## Declaration

```swift
struct DateFeatures
```

## Overview

Overview The choice of features for a particular task depends on the relevance of different date and time components. For example a dataset of weather data may require hour and day-of-year features, while a dataset of workout metrics may require second, hour, and weekday features.

## Topics
