【Excel函数与公式】DATE函数的用法解析 - 知乎

【Excel函数与公式】DATE函数的用法解析 - 知乎首发于知识聚变切换模式写文章登录/注册【Excel函数与公式】DATE函数的用法解析知识情报院Excel 中的DATE公式解析Date函数定义：使用年、月、日三个值来构造日期函数语法：=DATE(year,month,day)

year 为必需参数。 year 参数的值可以包含 1 到 4 个数字。 Excel 根据计算机使用的日期系统解释 year 参数。默认情况下，Microsoft Excel for Windows 使用 1900 日期系统，这意味着第一个日期是 1900 年 1 月 1 日。如果 year 介于 0（零）到 1899 之间（包含这两个值），则 Excel 会将该值与 1900 相加来计算年份。例如，DATE(108,1,2) 返回 2008 年 1 月 2 日 (1900+108)。如果 year 介于 1900 到 9999 之间（包含这两个值），则 Excel 将使用该数值作为年份。例如，DATE(2008,1,2)返回 2008 年 1 月 2 日。如果 year 小于 0 或大于 10000，Excel 将返回#NUM！错误值。Month 必需参数。一个正整数或负整数，表示一年中从 1 月至 12 月（一月到十二月）的各个月。如果 month 大于 12，则 month 会从指定年份的第一个月开始加上该月份数。例如，DATE(2008,14,2) 返回表示 2009 年 2 月 2 日的序列数。如果 month 小于 1，则 month 会从指定年份的第一个月开始减去该月份数，然后再加上 1 个月。例如，DATE(2008,-3,2)返回表示 2007 年 9 月 2 日的序列号。Day 必需参数。一个正整数或负整数，表示一月中从 1 日到 31 日的各天。如果 day 大于指定月中的天数，则 day 会从该月的第一天开始加上该天数。例如，DATE(2008,1,35) 返回表示 2008 年 2 月 4 日的序列数。如果 day 小于 1，则 day 从指定月份的第一天开始减去该天数，然后再加上 1 天。例如，DATE(2008,1,-15) 返回表示 2007 年 12 月 16 日的序列号。示例1：直接引用数值=DATE(1999,1,1) // 返回 1999年1月1日

=DATE(2021,6,1) // 返回 2021年6月1日

示例2：:单元格引用数值=DATE(A1,4,15) // 返回2021年4月15日

示例3：与Sumifs、Countifs嵌套使用=COUNTIF(A3:A16,">"&DATE(A1,B1,C1))

示例4：计算今年任意月份的天数，如2月=DAY(DATE(YEAR(TODAY()),3,1)-1)

//1、首先获取到今年3月1日的日期，减去1，即2月最后1天的日期

//2、再使用DAY函数提取日期中的天，即得到2月的天数

new Date(value);

new Date(dateString);

new Date(year, monthIndex [, day [, hours [, minutes [, seconds [, milliseconds]]]]]);

备注：创建一个新Date对象的唯一方法是通过new 操作符，例如：let now = new Date();

若将它作为常规函数调用（即不加 new 操作符），将返回一个字符串，而非 Date 对象。

参数Date()构造函数有四种基本形式

没有参数

如果没有提供参数，那么新创建的 Date 对象表示实例化时刻的日期和时间。

Unix 时间戳

value

一个 Unix 时间戳（Unix Time Stamp），它是一个整数值，表示自 1970 年 1 月 1 日 00:00:00 UTC（the Unix epoch）以来的毫秒数，忽略了闰秒。请注意大多数 Unix 时间戳功能仅精确到最接近的秒。

时间戳字符串 dateString

表示日期的字符串值。该字符串应该能被 Date.parse() 正确方法识别（即符合 IETF-compliant RFC 2822 timestamps 或 version of ISO8601）。

备注：由于浏览器之间的差异与不一致性，强烈不推荐使用Date构造函数来解析日期字符串 (或使用与其等价的Date.parse)。对 RFC 2822 格式的日期仅有约定俗成的支持。对 ISO 8601 格式的支持中，仅有日期的串 (例如 "1970-01-01") 会被处理为 UTC 而不是本地时间，与其他格式的串的处理不同。

分别提供日期与时间的每一个成员

当至少提供了年份与月份时，这一形式的 Date() 返回的 Date 对象中的每一个成员都来自下列参数。没有提供的成员将使用最小可能值（对日期为1，其他为0）。

year

表示年份的整数值。0 到 99 会被映射至 1900 年至 1999 年，其他值代表实际年份。参见示例。

monthIndex

表示月份的整数值，从 0（1 月）到 11（12 月）。

date可选

表示一个月中的第几天的整数值，从 1 开始。默认值为 1。

hours 可选

表示一天中的小时数的整数值 (24 小时制)。默认值为 0（午夜）。

minutes 可选

表示一个完整时间（如 01:10:00）中的分钟部分的整数值。默认值为 0。

seconds 可选

表示一个完整时间（如 01:10:00）中的秒部分的整数值。默认值为 0。

milliseconds 可选

表示一个完整时间的毫秒部分的整数值。默认值为 0。

使用注释

备注：参数monthIndex 是从“0”开始计算的，这就意味着一月份为“0”，十二月份为“11”。

备注：当 Date 作为构造函数调用并传入多个参数时，如果数值大于合理范围时（如月份为 13 或者分钟数为 70），相邻的数值会被调整。比如 new Date(2013, 13, 1) 等于 new Date(2014, 1, 1)，它们都表示日期 2014-02-01（注意月份是从 0 开始的）。其他数值也是类似，new Date(2013, 2, 1, 0, 70) 等于 new Date(2013, 2, 1, 1, 10)，都表示同一个时间：2013-03-01T01:10:00。

备注：当 Date 作为构造函数调用并传入多个参数时，所定义参数代表的是当地时间。如果需要使用世界协调时 UTC，使用 new Date(Date.UTC(...)) 和相同参数。

简介

如果没有输入任何参数，则 Date 的构造器会依据系统设置的当前时间来创建一个 Date 对象。

如果提供了至少两个参数，其余的参数均会默认设置为 1（如果没有指定 day 参数）或者 0（如果没有指定 day 以外的参数）。

JavaScript 的时间由世界标准时间（UTC）1970 年 1 月 1 日开始，用毫秒计时，一天由 86,400,000 毫秒组成。Date 对象的范围是 -100,000,000 天至 100,000,000 天（等效的毫秒值）。

Date 对象为跨平台提供了统一的行为。时间属性可以在不同的系统中表示相同的时刻，而如果使用了本地时间对象，则反映当地的时间。

Date 对象支持多个处理 UTC 时间的方法，也相应地提供了应对当地时间的方法。UTC，也就是我们所说的格林威治时间，指的是 time 中的世界时间标准。而当地时间则是指执行 JavaScript 的客户端电脑所设置的时间。

以一个函数的形式来调用 Date 对象（即不使用 new 操作符）会返回一个代表当前日期和时间的字符串。

属性

Date.prototype (en-US)

允许为 Date 对象添加属性。

Date.length

Date.length 的值是 7。这是该构造函数可接受的参数个数。

方法

Date.now()

返回自 1970-1-1 00:00:00 UTC（世界标准时间）至今所经过的毫秒数。

Date.parse()

解析一个表示日期的字符串，并返回从 1970-1-1 00:00:00 所经过的毫秒数。

备注：由于浏览器差异和不一致，强烈建议不要使用Date.parse解析字符串。

Date.UTC()

接受和构造函数最长形式的参数相同的参数（从 2 到 7），并返回从 1970-01-01 00:00:00 UTC 开始所经过的毫秒数。

JavaScript Date 实例所有的 Date 实例都继承自 Date.prototype (en-US)。修改 Date 构造函数的原型对象会影响到所有的 Date 实例。实例属性

Date.prototype.constructor

返回创建了实例的构造函数，默认是 Date 构造函数。

示例创建一个日期对象的几种方法下例展示了用来创建一个日期对象的多种方法。

备注：由于浏览器差异和不一致性，强烈建议不要使用Date构造函数（和Date.parse，它们是等效的）解析日期字符串。

jsvar today = new Date();

var birthday = new Date("December 17, 1995 03:24:00");

var birthday = new Date("1995-12-17T03:24:00");

var birthday = new Date(1995, 11, 17);

var birthday = new Date(1995, 11, 17, 3, 24, 0);

将两位数年份映射为 1900 - 1999 年为了创建和获取 0 到 99 之间的年份，应使用 Date.prototype.setFullYear() 和 Date.prototype.getFullYear() 方法。

jsvar date = new Date(98, 1); // Sun Feb 01 1998 00:00:00 GMT+0000 (GMT)

// 已弃用的方法，同样将 98 映射为 1998

date.setYear(98); // Sun Feb 01 1998 00:00:00 GMT+0000 (GMT)

date.setFullYear(98); // Sat Feb 01 0098 00:00:00 GMT+0000 (BST)

计算经过的时间下例展示了如何以毫秒精度计算两个日期对象的时间差：

由于不同日期、月份、年份长度的不同（日期长度不同来自夏令时的切换），使用大于秒、分钟、小时的单位表示经过的时间会遇到很多问题，在使用前需要经过详尽的调研。

js// 使用 Date 对象

var start = Date.now();

// 调用一个消耗一定时间的方法：

doSomethingForALongTime();

var end = Date.now();

var elapsed = end - start; // 以毫秒计的运行时长

js// 使用内建的创建方法

var start = new Date();

// 调用一个消耗一定时间的方法：

doSomethingForALongTime();

var end = new Date();

var elapsed = end.getTime() - start.getTime(); // 运行时间的毫秒值

js// to test a function and get back its return

function printElapsedTime(fTest) {

var nStartTime = Date.now(),

vReturn = fTest(),

nEndTime = Date.now();

alert("Elapsed time: " + String(nEndTime - nStartTime) + " milliseconds");

return vReturn;

Date objects encapsulate an integral number that represents milliseconds since the midnight at the beginning of January 1, 1970, UTC (the epoch).

Note: TC39 is working on Temporal, a new Date/Time API. Read more about it on the Igalia blog. It is not yet ready for production use!

DescriptionThe epoch, timestamps, and invalid dateA JavaScript date is fundamentally specified as the time in milliseconds that has elapsed since the epoch, which is defined as the midnight at the beginning of January 1, 1970, UTC (equivalent to the UNIX epoch). This timestamp is timezone-agnostic and uniquely defines an instant in history.

Note: While the time value at the heart of a Date object is UTC, the basic methods to fetch the date and time or its components all work in the local (i.e. host system) time zone and offset.

The maximum timestamp representable by a Date object is slightly smaller than the maximum safe integer (Number.MAX_SAFE_INTEGER, which is 9,007,199,254,740,991). A Date object can represent a maximum of ±8,640,000,000,000,000 milliseconds, or ±100,000,000 (one hundred million) days, relative to the epoch. This is the range from April 20, 271821 BC to September 13, 275760 AD. Any attempt to represent a time outside this range results in the Date object holding a timestamp value of NaN, which is an "Invalid Date".

jsconsole.log(new Date(8.64e15).toString()); // "Sat Sep 13 275760 00:00:00 GMT+0000 (Coordinated Universal Time)"

console.log(new Date(8.64e15 + 1).toString()); // "Invalid Date"

There are various methods that allow you to interact with the timestamp stored in the date:

You can interact with the timestamp value directly using the getTime() and setTime() methods.

The valueOf() and [@@toPrimitive]() (when passed "number") methods — which are automatically called in number coercion — return the timestamp, causing Date objects to behave like their timestamps when used in number contexts.

All static methods (Date.now(), Date.parse(), and Date.UTC()) return timestamps instead of Date objects.

The Date() constructor can be called with a timestamp as the only argument.

Date components and time zonesA date is represented internally as a single number, the timestamp. When interacting with it, the timestamp needs to be interpreted as a structured date-and-time representation. There are always two ways to interpret a timestamp: as a local time or as a Coordinated Universal Time (UTC), the global standard time defined by the World Time Standard. The local timezone is not stored in the date object, but is determined by the host environment (user's device).

Note: UTC should not be confused with the Greenwich Mean Time (GMT), because they are not always equal — this is explained in more detail in the linked Wikipedia page.

For example, the timestamp 0 represents a unique instant in history, but it can be interpreted in two ways:

As a UTC time, it is midnight at the beginning of January 1, 1970, UTC,

As a local time in New York (UTC-5), it is 19:00:00 on December 31, 1969.

The getTimezoneOffset() method returns the difference between UTC and the local time in minutes. Note that the timezone offset does not only depend on the current timezone, but also on the time represented by the Date object, because of daylight saving time and historical changes. In essence, the timezone offset is the offset from UTC time, at the time represented by the Date object and at the location of the host environment.

There are two groups of Date methods: one group gets and sets various date components by interpreting the timestamp as a local time, while the other uses UTC.

The Date() constructor can be called with two or more arguments, in which case they are interpreted as the year, month, day, hour, minute, second, and millisecond, respectively, in local time. Date.UTC() works similarly, but it interprets the components as UTC time and also accepts a single argument representing the year.

Note: Some methods, including the Date() constructor, Date.UTC(), and the deprecated getYear()/setYear() methods, interpret a two-digit year as a year in the 1900s. For example, new Date(99, 5, 24) is interpreted as June 24, 1999, not June 24, 99. See Interpretation of two-digit years for more information.

When a segment overflows or underflows its expected range, it usually "carries over to" or "borrows from" the higher segment. For example, if the month is set to 12 (months are zero-based, so December is 11), it become the January of the next year. If the day of month is set to 0, it becomes the last day of the previous month. This also applies to dates specified with the date time string format.Date time string formatThere are many ways to format a date as a string. The JavaScript specification only specifies one format to be universally supported: the date time string format, a simplification of the ISO 8601 calendar date extended format. The format is as follows:

YYYY-MM-DDTHH:mm:ss.sssZ

YYYY is the year, with four digits (0000 to 9999), or as an expanded year of + or - followed by six digits. The sign is required for expanded years. -000000 is explicitly disallowed as a valid year.

MM is the month, with two digits (01 to 12). Defaults to 01.

DD is the day of the month, with two digits (01 to 31). Defaults to 01.

T is a literal character, which indicates the beginning of the time part of the string. The T is required when specifying the time part.

HH is the hour, with two digits (00 to 23). As a special case, 24:00:00 is allowed, and is interpreted as midnight at the beginning of the next day. Defaults to 00.

mm is the minute, with two digits (00 to 59). Defaults to 00.

ss is the second, with two digits (00 to 59). Defaults to 00.

sss is the millisecond, with three digits (000 to 999). Defaults to 000.

Z is the timezone offset, which can either be the literal character Z (indicating UTC), or + or - followed by HH:mm, the offset in hours and minutes from UTC.

Various components can be omitted, so the following are all valid:

Date-only form: YYYY, YYYY-MM, YYYY-MM-DD

Date-time form: one of the above date-only forms, followed by T, followed by HH:mm, HH:mm:ss, or HH:mm:ss.sss. Each combination can be followed by a time zone offset.

For example, "2011-10-10" (date-only form), "2011-10-10T14:48:00" (date-time form), or "2011-10-10T14:48:00.000+09:00" (date-time form with milliseconds and time zone) are all valid date time strings.

When the time zone offset is absent, date-only forms are interpreted as a UTC time and date-time forms are interpreted as local time. This is due to a historical spec error that was not consistent with ISO 8601 but could not be changed due to web compatibility. See Broken Parser – A Web Reality Issue.

Date.parse() and the Date() constructor both accept strings in the date time string format as input. Furthermore, implementations are allowed to support other date formats when the input fails to match this format.

The toISOString() method returns a string representation of the date in the date time string format, with the time zone offset always set to Z (UTC).

Note: You are encouraged to make sure your input conforms to the date time string format above for maximum compatibility, because support for other formats is not guaranteed. However, there are some formats that are supported in all major implementations — like RFC 2822 format — in which case their usage can be acceptable. Always conduct cross-browser tests to ensure your code works in all target browsers. A library can help if many different formats are to be accommodated.

Non-standard strings can be parsed in any way as desired by the implementation, including the time zone — most implementations use the local time zone by default. Implementations are not required to return invalid date for out-of-bounds date components, although they usually do. A string may have in-bounds date components (with the bounds defined above), but does not represent a date in reality (for example, "February 30"). Implementations behave inconsistently in this case. The Date.parse() page offers more examples about these non-standard cases.Other ways to format a date

toISOString() returns a string in the format 1970-01-01T00:00:00.000Z (the date time string format introduced above, which is simplified ISO 8601). toJSON() calls toISOString() and returns the result.

toString() returns a string in the format Thu Jan 01 1970 00:00:00 GMT+0000 (Coordinated Universal Time), while toDateString() and toTimeString() return the date and time parts of the string, respectively. [@@toPrimitive]() (when passed "string" or "default") calls toString() and returns the result.

toUTCString() returns a string in the format Thu, 01 Jan 1970 00:00:00 GMT (generalized RFC 7231).

toLocaleDateString(), toLocaleTimeString(), and toLocaleString() use locale-specific date and time formats, usually provided by the Intl API.

ExamplesSeveral ways to create a Date objectThe following examples show several ways to create JavaScript dates:

Note: Creating a date from a string has a lot of behavior inconsistencies. See date time string format for caveats on using different formats.

jsconst today = new Date();

const birthday = new Date("December 17, 1995 03:24:00"); // DISCOURAGED: may not work in all runtimes

const birthday2 = new Date("1995-12-17T03:24:00"); // This is standardized and will work reliably

const birthday3 = new Date(1995, 11, 17); // the month is 0-indexed

const birthday4 = new Date(1995, 11, 17, 3, 24, 0);

const birthday5 = new Date(628021800000); // passing epoch timestamp

Formats of toString method return valuesjsconst date = new Date("2020-05-12T23:50:21.817Z");

date.toString(); // Tue May 12 2020 18:50:21 GMT-0500 (Central Daylight Time)

date.toDateString(); // Tue May 12 2020

date.toTimeString(); // 18:50:21 GMT-0500 (Central Daylight Time)

date[Symbol.toPrimitive]("string"); // Tue May 12 2020 18:50:21 GMT-0500 (Central Daylight Time)

date.toISOString(); // 2020-05-12T23:50:21.817Z

date.toJSON(); // 2020-05-12T23:50:21.817Z

date.toUTCString(); // Tue, 12 May 2020 23:50:21 GMT

date.toLocaleString(); // 5/12/2020, 6:50:21 PM

date.toLocaleDateString(); // 5/12/2020

date.toLocaleTimeString(); // 6:50:21 PM

To get Date, Month and Year or Timejsconst date = new Date("2000-01-17T16:45:30");

const [month, day, year] = [

date.getMonth(),

date.getDate(),

date.getFullYear(),

];

// [0, 17, 2000] as month are 0-indexed

const [hour, minutes, seconds] = [

date.getHours(),

date.getMinutes(),

date.getSeconds(),

];

// [16, 45, 30]

Interpretation of two-digit yearsnew Date() exhibits legacy undesirable, inconsistent behavior with two-digit year values; specifically, when a new Date() call is given a two-digit year value, that year value does not get treated as a literal year and used as-is but instead gets interpreted as a relative offset — in some cases as an offset from the year 1900, but in other cases, as an offset from the year 2000.

jslet date = new Date(98, 1); // Sun Feb 01 1998 00:00:00 GMT+0000 (GMT)

date = new Date(22, 1); // Wed Feb 01 1922 00:00:00 GMT+0000 (GMT)

date = new Date("2/1/22"); // Tue Feb 01 2022 00:00:00 GMT+0000 (GMT)

// Legacy method; always interprets two-digit year values as relative to 1900

date.setYear(98);

date.toString(); // Sun Feb 01 1998 00:00:00 GMT+0000 (GMT)

date.setYear(22);

date.toString(); // Wed Feb 01 1922 00:00:00 GMT+0000 (GMT)

So, to create and get dates between the years 0 and 99, instead use the preferred setFullYear() and getFullYear() methods:.

js// Preferred method; never interprets any value as being a relative offset,

// but instead uses the year value as-is

date.setFullYear(98);

date.getFullYear(); // 98 (not 1998)

date.setFullYear(22);

date.getFullYear(); // 22 (not 1922, not 2022)

Calculating elapsed timeThe following examples show how to determine the elapsed time between two JavaScript dates in milliseconds.

Due to the differing lengths of days (due to daylight saving changeover), months, and years, expressing elapsed time in units greater than hours, minutes, and seconds requires addressing a number of issues, and should be thoroughly researched before being attempted.

js// Using Date objects

const start = Date.now();

// The event to time goes here:

doSomethingForALongTime();

const end = Date.now();

const elapsed = end - start; // elapsed time in milliseconds

js// Using built-in methods

const start = new Date();

// The event to time goes here:

doSomethingForALongTime();

const end = new Date();

const elapsed = end.getTime() - start.getTime(); // elapsed time in milliseconds

js// To test a function and get back its return

function printElapsedTime(testFn) {

const startTime = Date.now();

const result = testFn();

const endTime = Date.now();

console.log(`Elapsed time: ${String(endTime - startTime)} milliseconds`);

return result;

}

const yourFunctionReturn = printElapsedTime(yourFunction);

Note: In browsers that support the Web Performance API's high-resolution time feature, Performance.now() can provide more reliable and precise measurements of elapsed time than Date.now().

Get the number of seconds since the ECMAScript Epochjsconst seconds = Math.floor(Date.now() / 1000);

In this case, it's important to return only an integer—so a simple division won't do. It's also important to only return actually elapsed seconds. (That's why this code uses Math.floor(), and not Math.round().)SpecificationsSpecificationECMAScript Language Specification # sec-date-objectsBrowser compatibilityBCD tables only load in the browser with JavaScript enabled.
