Function day in excel

This article describes the formula syntax and usage of the DAY function in Microsoft Excel. For information about the DAYS function, see DAYS function.

Description

Returns the day of a date, represented by a serial number. The day is given as an integer ranging from 1 to 31.

Syntax

DAY(serial_number)

The DAY function syntax has the following arguments:

• Serial_number    Required. The date of the day you are trying to find. Dates should be entered by using the DATE function, or as results of other formulas or functions. For example, use DATE(2008,5,23) for the 23rd day of May, 2008. Problems can occur if dates are entered as text.

Remarks

Microsoft Excel stores dates as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900.

Values returned by the YEAR, MONTH and DAY functions will be Gregorian values regardless of the display format for the supplied date value. For example, if the display format of the supplied date is Hijri, the returned values for the YEAR, MONTH and DAY functions will be values associated with the equivalent Gregorian date.

Example

Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.

Date
15-Apr-11
Formula	Description (Result)	Result
=DAY(A2)	Day of the date in cell A2 (15)	15

The DAY function has a simple purpose when used by itself. It gives you the «day» component (i.e., a number from 1-31) of a date inside a cell. However, the DAY function allows us to play around with dates in our worksheets by using it with some logical arguments or other functions, as will see in the examples section.

But first, let’s get some basics out of the way.

Syntax

The syntax of the DAY function is as follows:

=DAY(serial_number)

Arguments:

serial_number – The DAY function has just one argument, where you will need to enter a date, either in the form of a serial number or cell reference.

Important Characteristics of the DAY function

• The DAY function extracts the day from a given date and returns it into a cell.
• The DAY function can be nested inside another function to relay the return (for example, in the DATE function).
• If the cell referenced in the serial_number argument does not contain a valid Excel date, the function will return a #VALUE! error.

Examples of the DAY function

Now let’s have a look at some of the examples of the DAY function in Excel.

Example 1 – Plain-vanilla DAY formula

Let’s use the DAY function to extract a day from a date without adding any other complexities. Here is the formula we will use:

=DAY(A2)

No rocket science, right? We have a date in cell A2, and we use the DAY function to extract the day from that date, which is ’25.’

Example 2 – Finding the Number of Days in a Month with DAY function

The formula we will use here is pretty simple. It has a 2-step process and involves 2 functions: DAY and EOMONTH.

We know how the DAY function works. Let’s talk about the EOMONTH function.

The EOMONTH function has 2 arguments. In the first argument, you must supply a date, and in the second argument, you must supply the number of months you want to add to that date.

The EOMONTH function returns the last date of the month, after adding the specified number of months to the given date. For example, if we supply the start date as «12/25/2001» and enter 1 in the second argument, the EOMONTH function will return 01/31/2002.

Alright, now that we have the EOMONTH function covered, let’s look at the formula for finding the number of days in a given month:

=DAY(EOMONTH(A2, 0))

Since our start date is 12/25/2001, the EOMONTH will return 12/31/2001. Also, we know that the DAY function returns the day component of a date, and therefore, it will return ’31,’ i.e. the number of days in December.

Example 3 – Adding Days, Months, or Years with DAY and DATE function

Okay, so let’s say we have a list of dates and a list of days/months/years that we want to add to those dates.

To accomplish this, we will nest the YEAR, MONTH & DAY functions inside the DATE function and add the relevant argument with the corresponding year, month or day to be added. So the formula would be :

=DATE(YEAR(A2) + D2, MONTH(A2) + C2, DAY(A2) + B2)

Essentially, we are trying to add 0 years (from cell D2 to the first argument), 0 months (from cell C2 to the second argument), and 5 days (from cell B2 to the third argument) of the date function. When this formula is dragged down using the fill-handle it populates the correct formula against each row and gives us the suitable output.

Note that instead of putting a number for the years, months, or days to be added in a separate cell, we could just use the number in the formula after the ‘+’ sign instead of referencing the cell.

Example 4 – Fetch the nth Weekday in a Given Month

Let’s say we are trying to find out 2nd and 4th Saturdays in a month, for this we can make use of the DAY and WEEKDAY functions.

We’ll prepare the formula as:

=A2 – DAY(A2) + 1 + n * 7 – WEEKDAY(A2 – DAY(A2) + 8 – 7)

Like we always do, let’s dismantle this formula and understand what each component contributes to the final output.

Step 1

A2 is the start date. From A2, we will subtract the date itself using the DAY function and then add 1.

Why?

Well, all we want to do in this part of the formula is bring the formula to the 1^st day of the month. In our example, cell A2 contains the date 12/22/2001. Removing 22 days using the DAY function, and adding 1, gives us 12/01/2001.

Step 2

Great, so the next component of the formula is n * 7. ‘n’ here is the occurrence of the day in a given month that we want to compute. In our example, we want the 2^nd and 4^th Saturday of the given months, so we will set our n to ‘2’ and ‘4’. In effect, this computation will take us ‘n’ number of weeks into a given month.

We will now continue our discussion with the list of 2^nd Saturdays, but the logic remains the same for both lists.

In step 1, we navigated to the 1^st date of the month. Now, what should we add to this to reach the last day of the nth week? Just the number of weeks multiplied by the number of days in a week, right? So, we will add 14 days (2 * 7) for our list of 2^nd Saturdays.

This brings our formula to 12/15/2001.

Step 3

The final step. Now that we have navigated n number of weeks into a given month, let’s navigate to the specific day we want.

While 12/15/2001 (as computed in Step 2) also happens to be a Saturday, it is the 3^rd Saturday of the month.

So, we will use the WEEKDAY function to backtrack to the intended day. WEEKDAY returns a number from 1 to 7 in which 1 represents a Sunday, and 7 represents a Saturday.

In our example, the WEEKDAY function returns a ‘7.’

Why does WEEKDAY return 7?

The ‘7’ represents the weekday as on the first date in a given month since, within the WEEKDAY function, we navigate to the first day using the DAY function and then add 1.

So, let’s subtract 7 from 12/15/2001 to get our final output.

We get 12/08/2001, which is the 2^nd Saturday; the first Saturday being 12/01/2001.

Example 5 – Get the First Day of the Month with DAY function

I sort of gave this away in the previous example, but let’s quickly recap through how we can compute the first day of the month using the DAY function.

We will use the following formula:

=A2 – DAY(A2) + 1

Does this look familiar? We used this formula in our previous example, too.

A2 is our start day. When we use the DAY function and reference cell A2 in the argument, we are essentially asking it to fetch the day component of the date.

In our example, our start date is December 25, and the DAY function returns 25. Subtracting 25 days from December 25 will give us November 30, so we add 1 and get our final output as 12/01/2001, i.e. the first day of the month.

That’s a wrap on DAY function. When you are done playing around with the DAY function and ace these formulas, we will have another exciting Excel function for you. Until then, keep crunching those numbers.

Функция DAY (ДЕНЬ) используется в Excel, для того чтобы узнать порядковый номер дня месяца (в промежутке от 1 до 31) из любой даты.

Что функция возвращает

Возвращает число в промежутке от 0 до 31, в зависимости от даты, из которой требуется извлечь данные. Например, возвращая данные для Февраля, формула вернет номер дня в промежутке от «0» до «29».

Синтаксис

=DAY(serial_number)

=ДЕНЬ(дата_в_числовом_формате)

Аргументы функции DAY (ДЕНЬ) в Excel

• serial_number (дата_в_числовом_формате): Это порядковый номер дня. Он может быть результатом вычисления формулы, ссылкой на ячейку, которая содержит дату или данные введенные вручную.

Дополнительная информация

Помимо введенных в ручную чисел, функция DAY (ДЕНЬ) также будет работать с:

• результатами вычислений;
• датой введенной в текстовом формате (в кавычках);
• датой, указанной в текстовом формате;
• Excel отразит любую дату начиная с 1 Января 1900 года на Windows и с 1904 года на Mac.

Примеры использования функции DAY (ДЕНЬ) в Excel

Пример №1. Получаем значение дня используя числовой аргумент

На примере выше в качестве аргумента мы используем число “42736”. Это порядковый номер даты “1 января 2017”. Так как 1 января это первый день месяца, то результатом вычисления будет “1”.

Пример №2. Получаем значение дня из ячейки с датой

На примере выше, функция принимает значение ячейки с конкретной датой и возвращает номер дня месяца этой даты. Обратите внимание, что если вы используете формат даты, который не распознается Excel, он покажет ошибку.

Пример №3. Получаем значение дня текущей даты

Вы можете легко получить текущее значение дня с помощью функции TODAY (СЕГОДНЯ) в качестве исходных данных. Функция TODAY (СЕГОДНЯ) возвращает текущую дату, а DAY (ДЕНЬ), в свою очередь, использует эти данные, чтобы вернуть порядковый номер дня этого месяца.

На примере выше, функция TODAY(СЕГОДНЯ) возвращает 12-02-2017. Функция DAY (ДЕНЬ) принимает значение функции TODAY (СЕГОДНЯ) как вводные данные и возвращает значение “12” как порядковый номер дня этого месяца.

Пример №4. Получаем значение первого дня месяца

Вы также можете вычислить значение первого дня любого месяца.

На примере выше, значение дня для даты в ячейке “A2” — “15-03-2017” равно “15”. Для того чтобы узнать номер первого дня месяца этой даты, нам нужно вычесть из нее значение дня (получим “0”, т.к. все даты хранятся в Excel как порядковые номера) и прибавить “1”, чтобы получить первый день месяца.

Обратите внимание, что даты в ячейках D2 и D3 отформатированы как даты. Может случиться так, что, когда вы используете эту формулу, вы можете получить серийный номер (например, “42795” за 1 марта 2017 года). Затем вы можете просто отформатировать его в качестве даты.

How to Use the DAY function in Excel

Get the day of a date in numeric form

What to Know

• Syntax for function: DAY(serial_number).
• Enter date in spreadsheet > select cell > select Formulas > Date & Time > DAY > Serial_number > choose cell.
• If not working, select date column > right-click and select Format Cells > Number tab > Number > OK.

This article explains how to use the DAY function in Microsoft Excel to return a date as a serial number using an integer between 1 and 31.

How to Use the DAY function in Excel 

The syntax for the DAY function is DAY(serial_number).

The only argument for the DAY function is serial_number, which is required. This serial number field refers to the date of the day you are trying to find.

Dates are serial numbers in Excel’s internal system. Beginning with January 1, 1900 (which is number 1), each serial number is assigned in ascending numerical order. For example, January 1, 2008 is serial number 39448 because it is 39447 days after January 1, 1900.

Excel uses the serial number entered to determine which day of the month the date falls on. The day is returned as an integer ranging from 1 to 31.

1. Enter a date in an Excel spreadsheet using the DATE function. You can also use dates appearing as the result of other formulas or functions.

   If dates are entered as text, the DAY function might not work as it should.

2. Select the cell where you want the day of the date to appear.

3. Select Formulas. In Excel Online, select the Insert Function button next to the formula bar to open the Insert Function dialog box.

4. Select Date & Time to open the Function drop-down list. In Excel Online, choose Date & Time in the Pick a Category list. 

5. Select DAY in the list to bring up the function’s dialog box.

6. Make sure the Serial_number field is selected and then choose the cell containing the date you want to use.

7. Choose OK to apply the function and view the number representing the day of the date.

DAY Function Not Working

If your results are not appearing as numbers but rather as dates, it is likely a simple formatting issue. Problems could occur if the numbers are formatted as text rather than dates. Checking the format for the cells containing the serial number portion of the DAY function syntax (and then changing the format, if necessary) is the most likely way to resolve an error or incorrect result.

1. Select the column containing the dates.

2. Right-click anywhere on the selected cells and select Format Cells.

3. Make sure the Number tab is selected and choose Number in the Category list.

4. Select OK to apply the changes and close the dialog. Your results will appear as integers instead of dates.

When to Use the DAY Function in Excel

The DAY function is useful for financial analysis, primarily in a business setting. For instance, a retail organization might want to determine what day of the month has the highest number of customers or when most shipments arrive.

You can also extract a value using the DAY function inside of a larger formula. For instance, in this sample worksheet, the DAY function helps determine how many days are in the listed months.

The formula entered in cell G3 is

=DAY(EOMONTH(F3,0))

The DAY function provides the day component and EOMONTH (end of month) gives you the last day of the month for that date. The syntax for EOMONTH is EOMONTH(start_date, months). So the start date argument is the DAY entry and the number of months is 0, resulting in a list showing the number of days in the months presented.

Be careful not to confuse the DAY function with the DAYS function. The DAYS function, which uses the syntax DAYS(end_date, start_date) returns the number of days between a start date and an end date.

По умолчанию день 1 января 1900 г. имеет номер 1, а 28 февраля 2011 г. — номер 40602, так как интервал между этими датами составляет 40 602 дня. О том как EXCEL хранит дату и время, читайте эту
