by This is the final part of our Excel Date Tutorial that offers an overview of all Excel date functions, explains their basic uses and provides lots of formula examples.
Microsoft Excel provides a ton of functions to work with dates and times. Each function performs a simple operation and by combining several functions within one formula you can solve more complex and challenging tasks.
In the previous 12 parts of our Excel dates tutorial, we have studied the main Excel date functions in detail. In this final part, we are going to summarize the gained knowledge and provide links to a variety the formula examples to help you find the function best suited for calculating your dates.
The main function to calculate dates in Excel:
Get current date and time:
Convert dates to / from text:
Retrieve dates in Excel:
Calculate date difference:
Calculate workdays:
Excel DATE function
DATE(year, month, day) returns a serial number of a date based on the year, month and day values that you specify.
When it comes to working with dates in Excel, DATE is the most essential function to understand. The point is that other Excel date functions not always can recognize dates entered in the text format. So, when performing date calculations in Excel, you'd better supply dates using the DATE function to ensure the correct results.
Here are a few Excel DATE formula examples:
=DATE(2015, 5, 20) - returns a serial number corresponding to 20-May-2015.
=DATE(YEAR(TODAY()), MONTH(TODAY()), 1) - returns the first day of the current year and month.
=DATE(2015, 5, 20)-5 - subtracts 5 days from May 20, 2015.
At first sight, the Excel DATE function looks very simple, however, it does have a number of specificities pointed out in the Excel DATE tutorial.
Below you will find a few more examples where the Excel DATE function is part of bigger formulas:
Excel TODAY function
The TODAY() function returns today's date, exactly as its name suggests.
TODAY is arguably one of the easiest Excel functions to use because it has no arguments at all. Whenever you need to get today's date in Excel, enter the following formula is a cell:
=TODAY()
Apart from this obvious use, the Excel TODAY function can be part of more complex formulas and calculations based on today's date. For example, to add 7 days to the current date, enter the following formula in a cell:
=TODAY()+7
To add 30 weekdays to today's date excluding weekend days, use this one:
=WORKDAY(TODAY(), 30)
Note. The date returned by the TODAY function in Excel updates automatically when your worksheet is recalculated to reflect the current date.
For more formula examples demonstrating the use of the TODAY function in Excel, please check out the following tutorials:
Excel NOW function
NOW() function returns the current date and time. As well as TODAY, it does not have any arguments. If you wish to display today's date and current time in your worksheet, simply put the following formula in a cell:
=NOW()
Note. As well as TODAY, Excel NOW is a volatile function that refreshes the returned value every time the worksheet is recalculated. Please note, the cell with the NOW() formula does not auto update in real-time, only when the workbook is reopened or the worksheet is recalculated. To force the spreadsheet to recalculate, and consequently get your NOW formula to update its value, press either Shift+F9 to recalculate only the active worksheet or F9 to recalculate all open workbooks.
For more details, please see How to use NOW function in Excel.
Excel DATEVALUE function
DATEVALUE(date_text) converts a date in the text format to a serial number that represents a date.
The DATEVALUE function understands plenty of date formats as well as references to cells that contain "text dates". DATEVALUE comes in really handy to calculate, filter or sort dates stored as text and convert such "text dates" to the Date format.
A few simple DATEVALUE formula examples follow below:
=DATEVALUE("20-may-2015")
=DATEVALUE("5/20/2015")
=DATEVALUE("may 20, 2015")
And the following examples demonstrate how the DATEVALUE function can help with solving real-life tasks:
Excel TEXT function
In the pure sense, the TEXT function cannot be classified as one of Excel date functions because it can convert any numeric value, not only dates, to a text string.
With the TEXT(value, format_text) function, you can change the dates to text strings in a variety of formats, as demonstrated in the following screenshot.
Note. Though the values returned by the TEXT function may look like usual Excel dates, they are text values in nature and therefore cannot be used in other formulas and calculations.
Here are a few more TEXT formula examples that you may find helpful:
Excel DAY function
DAY(serial_number) function returns a day of the month as an integer from 1 to 31.
Serial_number is the date corresponding to the day you are trying to get. It can be a cell reference, a date entered by using the DATE function, or returned by other formulas.
Here are a few formula examples:
=DAY(A2) - returns the day of the month from a date in A2
=DAY(DATE(2015,1,1)) - returns the day of 1-Jan-2015
=DAY(TODAY()) - returns the day of today's date
Excel MONTH function
MONTH(serial_number) function in Excel returns the month of a specified date as an integer ranging from 1 (January) to 12 (December).
For example:
=MONTH(A2) - returns the month of a date in cell A2.
=MONTH(TODAY()) - returns the current month.
The MONTH function is rarely used in Excel date formulas on its own. Most often you would utilize it in conjunction with other functions as demonstrated in the following examples:
For the detail explanation of the MONTH function's syntax and plenty more formula examples, please check out the following tutorial: Using the MONTH function in Excel.
Excel YEAR function
YEAR(serial_number) returns a year corresponding to a given date, as a number from 1900 to 9999.
The Excel YEAR function is very straightforward and you will hardly run into any difficulties when using it in your date calculations:
=YEAR(A2) - returns the year of a date in cell A2.
=YEAR("20-May-2015") - returns the year of the specified date.
=YEAR(DATE(2015,5,20)) - a more reliable method to get the year of a given date.
=YEAR(TODAY()) - returns the current year.
For more information about the YEAR function, please see:
Excel EOMONTH function
EOMONTH(start_date, months) function returns the last day of the month a given number of months from the start date.
Like most of Excel date functions, EOMONTH can operate on dates input as cell references, entered by using the DATE function, or results of other formulas.
A positive value in the months argument adds the corresponding number of months to the start date, for example:
=EOMONTH(A2, 3) - returns the last day of the month, 3 months after the date in cell A2.
A negative value in the months argument subtracts the corresponding number of months from the start date:
=EOMONTH(A2, -3) - returns the last day of the month, 3 months before the date in cell A2.
A zero in the months argument forces the EOMONTH function to return the last day of the start date's month:
=EOMONTH(DATE(2015,4,15), 0) - returns the last day in April, 2015.
To get the last day of the current month, enter the TODAY function in the start_date argument and 0 in months:
=EOMONTH(TODAY(), 0)
You can find a few more EOMONTH formula examples in the following articles:
Excel WEEKDAY function
WEEKDAY(serial_number,[return_type]) function returns the day of the week corresponding to a date, as a number from 1 (Sunday) to 7 (Saturday).
- Serial_number can be a date, a reference to a cell containing a date, or a date returned by some other Excel function.
- Return_type (optional) - is a number that determines which day of the week shall be considered the first day.
You can find the complete list of available return types in the following tutorial: Day of the week function in Excel.
And here are a few WEEKEND formula examples:
=WEEKDAY(A2) - returns the day of the week corresponding to a date in cell A2; the 1st day of the week is Sunday (default).
=WEEKDAY(A2, 2) - returns the day of the week corresponding to a date in cell A2; the week begins on Monday.
=WEEKDAY(TODAY()) - returns a number corresponding to today's day of the week; the week begins on Sunday.
The WEEKDAY function can help you determine which dates in your Excel sheet are working days and which ones are weekend days, and also sort, filter or highlight workdays and weekends:
Excel DATEDIF function
DATEDIF(start_date, end_date, unit) function is specially designed to calculate the difference between two dates in days, months or years.
Which time interval to use for calculating the date difference depends on the letter you enter in the last argument:
=DATEDIF(A2, TODAY(), "d") - calculates the number of days between the date in A2 and today's date.
=DATEDIF(A2, A5, "m") - returns the number of complete months between the dates in A2 and B2.
=DATEDIF(A2, A5, "y") - returns the number of complete years between the dates in A2 and B2.
These are just the basic applications of the DATEDIF function and it is capable of much more, as demonstrated in the following examples:
Excel WEEKNUM function
WEEKNUM(serial_number, [return_type]) - returns the week number of a specific date as an integer from 1 to 53.
For example, the below formula returns 1 because the week containing January 1 is the first week in the year.
=WEEKNUM("1-Jan-2015")
The following tutorial explains all the specificities on the Excel WEEKNUM function: WEEKNUM function - calculating week number in Excel.
Alternatively you can skip directly to one of the formula examples:
Excel EDATE function
EDATE(start_date, months) function returns the serial number of the date that is the specified number of months before or after the start date.
For example:
=EDATE(A2, 5) - adds 5 months to the date in cell A2.
=EDATE(TODAY(), -5) - subtracts 5 months from today's date.
For a detailed explanation of EDATE formulas illustrated with formula examples, please see: How to use EDATE function in Excel.
Excel YEARFRAC function
YEARFRAC(start_date, end_date, [basis]) function calculates the proportion of the year between 2 dates.
This very specific function can be used to solve practical tasks such as calculating age from date of birth.
Excel WORKDAY function
WORKDAY(start_date, days, [holidays]) function returns a date N workdays before or after the start date. It automatically excludes weekend days from calculations as well as any holidays that you specify.
This function is very helpful for calculating milestones and other important events based on the standard working calendar.
For example, the following formula adds 45 weekdays to the start date in cell A2, ignoring holidays in cells B2:B8:
=WORKDAY(A2, 45, B2:B85)
For the detailed explanation of WORKDAY's syntax and more formula examples, please check out:
Excel WORKDAY.INTL function
WORKDAY.INTL(start_date, days, [weekend], [holidays]) is a more powerful variation of the WORKDAY function introduced in Excel 2010.
WORKDAY.INTL allows calculating a date N number of workdays in the future or in the past with custom weekend parameters.
For example, to get a date 20 workdays after the start date in cell A2, with Monday and Sunday counted as weekend days, you can use either of the following formulas:
=WORKDAY.INTL(A2, 20, 2, 7)
or
=WORKDAY.INTL(A2, 20, "1000001")
Of course, it might be difficult to grasp the essence from this short explanation, but more formula examples illustrated with screenshots will make things really easy:
Excel NETWORKDAYS function
NETWORKDAYS(start_date, end_date, [holidays]) function returns the number of weekdays between two dates that you specify. It automatically excludes weekend days and, optionally, the holidays.
For example, the following formula calculates the number of whole workdays between the start date in A2 and end date in B2, ignoring Saturdays and Sundays and excluding holidays in cells C2:C5:
=NETWORKDAYS(A2, B2, C2:C5)
You can find a comprehensive explanation of the NETWORKDAYS function's arguments illustrated with formula examples and screenshots in the following tutorial:
NETWORKDAYS function - calculating workdays between two dates
Excel NETWORKDAYS.INTL function
NETWORKDAYS.INTL(start_date, end_date, [weekend], [holidays]) is a more powerful modification of the NETWORKDAYS function available in Excel 2010 and later. It also returns the number of weekdays between two dates, but lets you specify which days should be counted as weekends.
Here is a basic NETWORKDAYS formula:
=NETWORKDAYS(A2, B2, 2, C2:C5)
The formula calculates the number of workdays between the date in A2 (start_date) and the date in B2 (end_date), excluding the weekend days Sunday and Monday (number 2 in the weekend parameter), and ignoring holidays in cells C2:C5.

I need a function that will return a value only if the specified day of the month is within a week ending column.
For example, I have a weekly cash flow forecast and I always pay my utility bill of $500 on the 15th of the month. I want a formula that will only return $500 when my week ending column includes the 15th of the month.
Please can you let me know if there is a formula I can use.
Thanks
I have Grade in excel needs to add next schedule date
for example
Grade A - add 180 days to the previous date (10/11/2015 + 180 days)
Grade B - add 365 days to the Previous date (10/10/2014 + 365 days)
Hi,
Is there a formula for counting workday from start date to end date, where end date =today() until an exact date is entered. Thanks.
Hi,
I want to create a employee attendance sheet with below details,
1. Set weekend by our choice any day of week like (Fri and Sat) instead of Sat and Sun
2. Holiday
3. auto changeable date if we select month and year
Please advise accordingly
Is there a formula that will allow me to open an excel file and it first of all create a NOW() DATE and then project a WEEK COMMENCING DATE for 4 weeks later
hi am looking for a formula that I can use in excel to highlight customer details on their payment days e.g if a customer make payments on Saturday a highlight on her details
Dear Esther,
(1) To highlight the cells whose dates math the weekday of any given day, go to Home - Conditional formatting - New rules - Select a rule type - Use a formula to determine which cells to format - Edit the rule description
In Edit the rule description, enter the below formula
=WEEKDAY(TODAY())=WEEKDAY(A1)
In Format - Fill, select the required colour.
Is this what you want to do?
(2) In case you want to highlight cells which matches the date on any given day, then type the below formula in Conditional Format.
=a1=today()

Hi, I need to have (todays date - 3) calculated in mmddyy format and inserted into a text field (e.g. "ABC/mmddyy_received". I will be really impressed if that is possible.
Hello Gordon,
You can use the TEXT function to convert the current date to text in any desired format, and concatenate the returned value with other text, e.g.:
="ABC/"&TEXT(TODAY(),"mmddyy")&"_received"
hi,
I'm looking for a formula in which computes the current year minus the previous year. I'm creating a table in which automatically compute the number of years or months.
example:
employee 1 starts: August 1, 2009 - current year
Employee 2 starts: Sept 1, 2015 - current year
Thank you,
Hi An,
You can use the DATEDIF function to calculate the difference between two dates in days, months or years.
If you are looking for something different, please specify exactly what results are expected in your example for employee 1 and employee 2.
Hi Meer,
You can use the NETWORKDAYS function, like =NETWORKDAYS(A2, B2), where A2 is the start date and B2 is the end date.
Hi,
I am looking for a formula which can give me the count for difference between start date and today's date which excludes weekend. For ex, if i want to see diffenence between 15th Sep 2015 and 21st sep 2015, i should get result as 5 excluding sunday.
Thanks,
Meer
I am looking for a formula which can add two years from the reference column date (DD-MM-YY) and and subtract three months from that, show up in next column.
Is it possible to color a the same output column with two different color based on starting of the date in this column and three months past from that day.
Thanks,

Is there a way to write a formula toe present yesterday to today? example present 8/13/2015 to 8/14/2015.
Hi Tony,
Sorry, I do not exactly understand the task. Do you want to "label" the dates as "present" (i.e. display the word "present" in another column in the same row) or are looking for something else?
I wanted to set a now date for when i open the sheet to calculate the date and add another value to another cell if the date is greater than a set date of each month i.e late fee applied in cell B3 if date is over the 5th
Forgot to mention that late fee applied in cell b3 if date is over the 5th but only if there is no value in A3.
A3=Payment made B3=Late fee If date is Now date is greater then 5th of each month
Thank you its working now!
Thank you!
It worked but P3 changes N2. Do you know what I've done wrong so that P3 changes N3 and so on
Thanks
Micky
Micky,
Make sure that the cell referenced in the formula corresponds to the first row in the rage to which the rule apples.
I.e. if your apply the rule beginning with row 2, use the formula I provided, if you apply the rule beginning with row 1 then replace P2 with P1 in the formula, and so on.
Hi,
I have used conditional formatting in Column N so that when today's date is past the date in each cell it changes to bold, red text.
In column P I have used conditional formatting to say that if I have tended to my outdated task as the following: equal to 'Y' is Green, equal to 'No answer' is yellow, equal to 'n' is red.
My question is:
If I enter either 'Y' or 'No answer' or 'N' into any cell in column P can this change the font in the corresponding cell in column 'N' back to regular, black text.
Hope you can help
Thanks
Micky
Hi!
You can create one more rule for column N with no formatting, and move it to the top of the rules' list:
=OR($P2="Y", $P2="N", $P2="No answer")
How can I enter the date with something like a TODAY function, but have the result fixed as it was on the day of entry, instead of volatile result that changes each time I open or refresh file?
Hi Brook,
There is no function in Excel that would let you enter the current date as a fixed unchangeable time stamp. You will need a VBA macro for this or you can use the shortcut Ctrl+;
If your goal is to get a static timestamp in your Excel sheet, then use one of the following shortcuts:
Ctrl + ; to insert the today's date in a cell.
Ctrl + Shift + ; to show the current time.
To display today's date and current time, please see Shortcuts to sho
Hi,
I need to know the formula to use if I want to get the earliest date from a row of dates. Example, I have 4 different dates, ( May 1, 2016 ; Sept. 2, 2015 ; August 19, 2018 and Sept 8, 2018). I need to get the earliest date from these 4 dates and it should show up. What formula do I need to use. Thanks.
Hi Florence,
You can use the MIN function, for example:
=MIN(A1:D1)
Where A1 to D1 are the cells containing the dates.
Hi Yasmeen,
You simply add 20 days to today's date:
=TODAY()+20
If the project duration numbers are stored in other cells, then you can refer to those cells in your formula, for example =TODAY()+B1 where B1 is Project duration.
hi
I want to know the upcoming specified date after numbers of days, like I want to know of project ending
project duration 20 days
project starts today
so when project will be finished in which date
thanks
Yasmeen
