When it comes to calculating dates in Excel, DATE is the most essential function to understand. As you probably know, Excel does not keep the year, month and day for a date, nor does it explicitly store weekday information in a cell. Instead, Microsoft Excel stores dates as serial numbers and this is the main source of confusion.

Not all Excel date functions can recognize dates entered as text values, therefore it's not recommended to supply dates directly in calculations. Instead, you should use the DATE function to get a serial number representing the date, the number that Excel understands and can operate on.

What the Excel DATE function does is return the serial number of a specified date. It has the following arguments:

DATE(year, month, day)

**Year** - represents the year of the date. Excel interprets the year argument according to the date system set up on your computer. By default, Microsoft Excel for Windows uses the 1900 system. In this date system:

- If year is between 1900 and 9999 inclusive, exactly that value is used for the year. For example,
`=DATE(2015, 12, 31)`

returns December 31, 2015. - If the year argument is between 0 and 1899 inclusive, Excel calculates the year by adding the specified number to 1900. For example,
`=DATE(100, 12, 31)`

returns December 31, 2000 (1900 + 100). - If year is less than 0 or greater than 9999, a DATE formula will return the #NUM! error.

**Month** - an integer representing the month of the year, from 1 (January) to 12 (December).

- If month is greater than 12, Excel adds that number to the first month in the specified year. For example,
`=DATE(2015, 15, 5)`

returns the serial number representing March 1, 2016 (January 5, 2015 plus 15 months). - If month is less than 1 (zero or negative value), Excel subtracts the magnitude of that number of months, plus 1, from the first month in the specified year. For example,
`=DATE(2015, -5, 1)`

returns the serial number representing July 1, 2014 (January 1, 2015 minus 6 months).

**Day** - an integer corresponding to the day of the month, from 1 to 31.

As well as month, the day argument can be supplied as a positive and negative number, and Excel calculates its value based on the same principles as described above.

The DATE function is available in all versions of Excel 2019, Excel 2016, Excel 2013, Excel 2010, and lower.

Below you will find a few examples of using DATE formulas in Excel beginning with the simplest ones.

This is the most obvious use of the DATE function in Excel.

For example, to return a serial number corresponding to 20-May-2015, use this formula:

`=DATE(2015, 5, 20)`

Instead of specifying the values representing the year, month and day directly in a formula, you can have some or all arguments driven by of other Excel date functions. For instance, combine the YEAR and TODAY to get a serial number for the first day of the current year.

`=DATE(YEAR(TODAY()), 1, 1)`

And this formula outputs a serial number for the first day of the current month in the current year:

`=DATE(YEAR(TODAY()), MONTH(TODAY(), 1)`

The DATE function is very helpful for calculating dates where the year, month, and day values are stored in other cells.

For example, to find the serial number for the date, taking the values in cells A2, A3 and A4 as the year, month and day arguments, respectively, the formula is:

`=DATE(A2, A3, A4)`

Another scenario when the Excel DATE function proves useful is when the dates are stored in the format that Microsoft Excel does not recognize, for instance DDMMYYYY. In this case, you can use DATE in liaison with other functions to convert a date stored as a numeric string or number into a date:

`=DATE(RIGHT(A2,4), MID(A2,3,2), LEFT(A2,2))`

As already mentioned, Microsoft Excel stores dates as serial numbers and operates on those numbers in formulas and calculations. That is why when you want to add or subtract some days to/from a given date, you need to convert that date to a serial number first by using the Excel DATE function. For example:

**Adding days**to a date:`=DATE(2015, 5, 20) + 15`

The formula adds 15 days to May 20, 2015 and returns June 4, 2015.

**Subtracting days**from a date:`=DATE(2015, 5, 20) - 15`

The result of the above formula is May 5, 2015, which is May 20, 2015 minus 15 days.

- To subtract a date from today's date:
`=TODAY()-DATE(2015,5,20)`

The formula calculates how many days are between the current date and some other date that you specify.

If you are adding or subtracting two dates that are stored in some cells, then the formula is as simple as =A1+B1 or A1-B1, respectively.

For more information, please see:

And here are a few more examples where Excel DATE is used in combination with other functions in more complex formulas:

In case you want not only to calculate but also highlight dates in your Excel worksheets, then create conditional formatting rules based on DATE formulas.

Supposing you have a list of dates in column A and you want to shade dates that occurred earlier than 1-May-2015 in orange and those that occur after 31-May-2015 in green.

The DATE formulas you want are as follows:

Orange: `=$A2<DATE(2015, 5, 1)`

- highlights dates less than 1-May-2015

Green: `=$A2>DATE(2015, 5, 31)`

- highlights dates greater than 31-May-2015

For the detailed steps and more formula examples, please see How to conditionally format dates in Excel.

Though DATE is the main function to work with dates in Excel, a handful of other functions are available to tackle more specific tasks. You can find the links to in-depth tutorials at the end of this article.

Meanwhile, I'd like to present you our Date & Time Wizard - a quick and easy way to calculate dates in Excel. The beauty of this tool is that outputs the results as **formulas**, not values. Thus you have a kind of 'two birds, one stone' opportunity - get the result faster and learn Excel date functions along the way :)

The wizard can perform the following calculations:

**Add**years, months, weeks, days, hours, minutes and seconds to the specified date.**Subtract**years, months, weeks, days, hours, minutes and seconds from the specified date.- Calculate the
**difference**between two dates. - Get
**age**from the birthdate.

For example, here's how you can add 4 different units in cells B3:E3 to the date in A4. The formula in B4 is built in real-time as you change the conditions:

If you are curious to explore other capabilities of the wizard, feel free to download a 14-day trial version of the Ultimate Suite which includes this as well as 60 more time saving add-ins for Excel.

* Green - 25-100 days from valid date to decision date

I've tried a few variations of things with no luck and it's driving me insane!!

Thanks in advance

Hello

I am trying to create a table whereby I set one anticipated start date and this can then autofill other cells by putting in how many weeks after (eg. start date is 05.03.20 so if I put a 2 in the weeks column the date would show up as 19.03.20). Does anyone know if this is possible/how to do it?

Many thanks

Ella.

How can I from say cell N11 Up until I11 count all the days that art between as a total amount of days that have passed so far does my question make sense?

I have a start date and a end date but as the days in between get added in as time goes on they need to be subtracted from the amount of days in my days *total column*.

*Start* *End* *Total Days for project*

03/03/2020 dates dates dates 05/05/2020 Days passed/left?

I'm trying to look at a priority level = A (+2 days), B (+5 days), C (+10 days) or D (+20 days) (in column E) then add the corresponding number days (+# days to column K) from the date in column C. Example in column C I have "01 Jan 20" and in column E I have "B" therefore I want column K to automatic insert "06 Jan 20" which is the +5 days due to priority level "B" selected. Thank you in advance for your assistance.

Hello!

I noticed the smart quotes in your formula and I suppose they are the cause of the error. Please convert your smart quotes into the straight quotation marks, that should fix the problem. Also, you may check this Microsoft manual to learn how to disable smart quotes: https://support.microsoft.com/en-us/office/smart-quotes-in-word-702fc92e-b723-4e3d-b2cc-71dedaf2f343

Check the formula. I have this formula

=IF(D3="","",IF(N3="Deceased",(DAYS(M3,I3)),(IF(L3="",(DAYS(TODAY(),I3)),DAYS(L3,I3)))))

I hope this will help, otherwise please do not hesitate to contact me anytime.
