## Discussion

Discussion The exact format depends on the locale. Possible values of date interval style include: omitted, numeric, abbreviated, long, and complete. The following code sample shows a variety of date interval style format results using the en_US locale. if let today = Calendar.current.date(byAdding: .day, value: -120, to: Date()),    let thirtyDaysBeforeToday = Calendar.current.date(byAdding: .day, value: -30, to: today) {    // today: Apr 11, 2021 at 7:14 AM    // thirtyDaysBeforeToday: Mar 12, 2021 at 7:14 AM

// Create a Range<Date>.    let last30days = thirtyDaysBeforeToday..<today          last30days.formatted(date: .omitted, time: .standard) // 3/12/2021, 7:11:16 AM – 4/11/2021, 7:11:16 AM

last30days.formatted(date: .numeric, time: .omitted) // 3/12/2021 – 4/11/2021

last30days.formatted(date: .abbreviated, time: .omitted) // Mar 12 – Apr 11, 2021

last30days.formatted(date: .long, time: .omitted) // March 12 – April 11, 2021"

last30days.formatted(date: .complete, time: .omitted) // Friday, March 12 – Sunday, April 11, 2021

last30days.formatted() // 3/12/21, 7:14 AM – 4/11/21, 7:14 AM } The default date style is numeric.
