# Date.FormatStyle.Symbol.Day

A type that specifies the format for a day in a date format style.

## Declaration

```swift
struct Day
```

## Overview

Overview The Date.FormatStyle.Symbol.Day type includes static factory variables and methods that create custom Date.FormatStyle.Symbol.Day objects:  |   |   |   |   |  To customize the day format in a string representation of a Date, use day(_:). The following example shows a variety of Date.FormatStyle.Symbol.Day formats applied to a date. let meetingDate = Date() // Feb 9, 2021 at 3:00 PM meetingDate.formatted(Date.FormatStyle().day(.defaultDigits)) // 9 meetingDate.formatted(Date.FormatStyle().day(.ordinalOfDayInMonth)) // 2 (second Tuesday of the month) meetingDate.formatted(Date.FormatStyle().day(.twoDigits)) // 09 meetingDate.formatted(Date.FormatStyle().day(.julianModified(minimumLength: 12))) // 0002459255 meetingDate.formatted(Date.FormatStyle().day()) // 9 If no format is specified as a parameter, the defaultDigits static variable is the default format. For more information about formatting dates, see the Date.FormatStyle.
