例  (3)

日付を揃える：

Wolfram Language code: ConformDates[{Yesterday, Now, DateObject[{2010}, "Year", "Gregorian", -6.]}]

日付を特定の粒度に揃える：

Wolfram Language code: ConformDates[{Yesterday, Now, DateObject[{2010}, "Year", "Gregorian", -6.]}, Now]

参照する日付を以下に準拠するテンプレートとして使用する：

Wolfram Language code: ConformDates[{DateObject[{2024, 8, 27, 4, 17, 40.7253}, "Instant", "Gregorian", -5.], DateObject[{2024, 1, 20, 23, 52, 30.6026}, "Instant", "Gregorian", -5.], DateObject[{2024, 9, 26, 9, 37, 22.0383}, "Instant", "Gregorian", -5.], DateObject[{2024, 1, 19, 11, 5, 28.6014}, "Instant", "Gregorian", -5.], DateObject[{2024, 5, 27, 7, 51, 30.4245}, "Instant", "Gregorian", -5.]}, DateObject[{"Reiwa", 6, 4, 30}, "Day", "Japanese", 0.]]

スコープ  (2)

ConformDatesは，DateObject式とTimeObject式には作用するが，DateList，DateString，AbsoluteTimeの指定には作用しない：

Wolfram Language code: Column[{#, ConformDates[ConstantArray[#[], 2]]}& /@ {DateObject, TimeObject, DateList, DateString, AbsoluteTime}]

参照とする日付が指定されている場合，DateGranularityやCalendarTypeのオプションは指定された日付から継承される：

Wolfram Language code: rdate = DateObject[{1445, 10, 21}, "Day", "Islamic", 0.];
Wolfram Language code: ConformDates[{DateObject[{2024, 4, 30, 0, 0, 0.}, "Instant", "Gregorian", -5.], DateObject[{2024, 5, 1, 0, 0, 0.}, "Instant", "Gregorian", -5.]}, rdate]
Wolfram Language code: opts = Rule[#, DateValue[rdate, ToString[#]]]& /@ {CalendarType, TimeZone, TimeSystem, DateFormat}
Wolfram Language code: ConformDates[{DateObject[{2024, 4, 30, 0, 0, 0.}, "Instant", "Gregorian", -5.], DateObject[{2024, 5, 1, 0, 0, 0.}, "Instant", "Gregorian", -5.]}, Sequence@@opts]

オプション  (5)

CalendarType  (1)

Wolfram Language code: ConformDates[{DateObject[{2022, 2, 15}, "Day"], DateObject[{2022, 2, 16}, "Day"], DateObject[{2022, 2, 14}, "Day"], DateObject[{2015}, "Year"], DateObject[{1950, 1, 4}, "Day", "Gregorian", -5.], DateObject[{2016, 3, 18, 10, 22, 10}, "Instant", "Gregorian", -3.], DateObject[{2017, 1, 1}, "Day"]}]

CalendarTypeオプションを使って出力に希望の暦が指定できる：

Wolfram Language code: ConformDates[{DateObject[{2022, 2, 15}, "Day"], DateObject[{2022, 2, 16}, "Day"], DateObject[{2022, 2, 14}, "Day"], DateObject[{2015}, "Year"], DateObject[{1950, 1, 4}, "Day", "Gregorian", -5.], DateObject[{2016, 3, 18, 10, 22, 10}, "Instant", "Gregorian", -3.], DateObject[{2017, 1, 1}, "Day"]}, CalendarType -> "Julian"]
