DateOverlapsQ[date1,date2]

如果日历日期 date1 和 date2 重合，返回 True，否则，返回 False.

更多信息

  • 在 DateOverlapsQ[date1,date2] 中，date1 和 date2 应被指定为任意日历粒度的 DateObject 表达式.
  • DateOverlapsQ 的两个参数都接受日期列表，实际上是对输入列表调用 Outer.
  • 如果 date1 和 date2 表示的时间段有任何重合，DateOverlapsQ 返回 True.

基本范例  (2)

Now 和 Today 是重合的：

Wolfram Language code: DateOverlapsQ[Today, Now]

但是 Now 和 Yesterday 不重合：

Wolfram Language code: DateOverlapsQ[Yesterday, Now]

测试给定的周是否与 2022 年 1 月重合：

Wolfram Language code: DateOverlapsQ[DateObject[{2022}, "Year"], DateObject[{2022, 5, 2}, "Week"]]

范围  (3)

查看一个日期是否与几个不同的日期重合：

Wolfram Language code: DateOverlapsQ[{Yesterday, Today, Tomorrow}, Now]

查看几个日期是否与给定日期重合：

Wolfram Language code: DateOverlapsQ[DateObject[{2022}, "Year"], {DateObject[{2022, 5, 9}, "Day"], DateObject[{2021, 8, 4}, "Day"], DateObject[{2022, 4}, "Month"]}]

查看几个日期是否与其他几个日期重合：

Wolfram Language code: DateOverlapsQ[{DateObject[{2022}, "Year"], DateObject[{2021, 12}, "Month"]}, {DateObject[{2022, 6, 17}, "Day"], DateObject[{2021, 12, 25}, "Day"], Entity["Country", "SouthKorea"][EntityProperty["Country", "IndependenceDate"]]}]

属性和关系  (3)

只要日期的任意部分重合，DateOverlapsQ 就返回 True：

Wolfram Language code: DateOverlapsQ[DateObject[{2022, 1}, "Month"], DateObject[{2022, 1, 31}, "Week"]]

只有当 date2 完全被包含在 date1 中时，DateWithinQ 才返回 True：

Wolfram Language code: DateWithinQ[DateObject[{2022, 1}, "Month"], DateObject[{2022, 1, 31}, "Week"]]

如果两个日期重合，它们的差将是以最大日历粒度计算得出的零：

Wolfram Language code: DateOverlapsQ[DateObject[{2022, 1}, "Month"], DateObject[{2022, 1, 31}, "Week"]]
Wolfram Language code: DateObject[{2022, 1, 31}, "Week"] - DateObject[{2022, 1}, "Month"]

如果两个日期对象重合，则无法对它们进行比较：

Wolfram Language code: DateOverlapsQ[DateObject[{2021, 8}, "Month"], DateObject[{2021, 8, 4}, "Day"]]
Wolfram Language code: DateObject[{2021, 8}, "Month"] < DateObject[{2021, 8, 4}, "Day"]
