## Count number of dates by year, month in Excel

When working on Excel worksheet, sometimes, you may want to count the cells where dates from a given year or month as below screenshot shown. To solve this task in Excel, you can use the SUMPRODUCT, YEAR and MONTH functions to create formulas to count the number of dates belongs to the specific year or month as you need.

**Count number of dates of given year****Count number of dates of given month****Count number of dates by both year and month**

** Count number of dates of given year **

To count the number of dates in a given year, you can combine the SUMPRODUCT and YEAR functions together, the generic syntax is:

**=SUMPRODUCT(--(YEAR(date_range)=year))**

**date_range**: A list of cells contain the dates you want to count;**year**: The value or cell reference that represents the year you want to count for.

**1**. Enter or copy the below formula into a blank cell where you want to get the result:

**=SUMPRODUCT(--(YEAR($A$2:$A$14)=C2))**

**Note**: In this formula, **A2:A14** is the range of cells contain the dates, **C2** contain the specific year you want to count for.

**2**. Then, drag the fill handle down to apply this formula to other cells, and you will get the number of dates based on the given year, see screenshot:

##### Explanation of the formula:

**=SUMPRODUCT(--(YEAR($A$2:$A$14)=C2))**

**YEAR($A$2:$A$14)=C2**: The YEAR function extracts the year value from the list of dates as this: {2020;2019;2020;2021;2020;2021;2021;2021;2019;2020;2021;2019;2021};

And then, each year is compared to the year value in cell C2, to return an array of TRUE and FALSE values: {FALSE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE}.**--(YEAR($A$2:$A$14)=C2)=--{FALSE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE}**: --this double negative sign converts TRUE value to 1 and False value to 0. So, you will get the result as this: {0;1;0;0;0;0;0;0;1;0;0;1;0}.**SUMPRODUCT(--(YEAR($A$2:$A$14)=C2))= SUMPRODUCT({0;1;0;0;0;0;0;0;1;0;0;1;0})**: Finally, this SUMPRODUCT function sums all the items in the array, and return the result: 3.

** Count number of dates of given month **

If you want to count the number of dates based on a given month, the SUMPRODUCT and MONTH functions may do you a favor, the generic syntax is:

**=SUMPRODUCT(--(MONTH(date_range)=month))**

**date_range**: A list of cells contain the dates you want to count;**month**: The value or cell reference that represents the month you want to count for.

**1**. Enter or copy the below formula into a blank cell where you want to get the result:

**=SUMPRODUCT(--(MONTH($A$2:$A$14)=C2))**

**Note**: In this formula, **A2:A14** is the range of cells contain the dates, **C2** contain the specific month you want to count for.

**2**. Then, drag the fill handle down to apply this formula to other cells, and you will get the number of dates based on the given month, see screenshot:

##### Explanation of the formula:

**=SUMPRODUCT(--(MONTH($A$2:$A$14)=C2))**

**MONTH($A$2:$A$14)=C2**: This MONTH function extracts the month number from the list of dates as this: {12;3;8;4;8;12;5;5;10;5;7;12;5}.

And then, each month is compared to the month number in cell C2, to return an array of TRUE and FALSE values: {FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;TRUE;TRUE;FALSE;TRUE;FALSE;FALSE;TRUE}.**--(MONTH($A$2:$A$14)=C2)= --{FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;TRUE;TRUE;FALSE;TRUE;FALSE;FALSE;TRUE}**: - -this double negative sign converts TRUE value to 1 and False value to 0. So, you will get the result as this: {0;0;0;0;0;0;1;1;0;1;0;0;1}.**SUMPRODUCT(--(MONTH($A$2:$A$14)=C2))= SUMPRODUCT({0;0;0;0;0;0;1;1;0;1;0;0;1})**: This SUMPRODUCT function sums all the items in the array, and return the result: 4.

** Count number of dates by both year and month **

For counting the number of dates based on both year and month, for example, I want to know how many dates are there in May 2021.

In this case, you can use a combination of SUMPRODUCT, MONTH and YEAR functions to get the result, the generic syntax is:

**=SUMPRODUCT((MONTH(date_range)=month)*(YEAR(date_range)=year))**

**date_range**: A list of cells contain the dates you want to count;**month**: The value or cell reference that represents the month you want to count for;**year**: The value or cell reference that represents the year you want to count for.

Please enter or copy the below formula into a blank cell to output the result, and then press **Enter** key to get the calculation, see screenshot:

**=SUMPRODUCT((MONTH($A$2:$A$14)=D2)*(YEAR($A$2:$A$14)=C2))**

**Note**: In the above formula, **A2:A14** is the range of cells contain the dates, **D2** contain the specific month and **C2** is the year number that you want to count for.

** Relative function used:**

**SUMPRODUCT:**- The SUMPRODUCT function can be used to multiply two or more columns or arrays together, and then get the sum of products.

**MONTH:**- The Excel MONTH function extracts the month from a date and displays as integer number from 1 to 12.

**YEAR:**- The YEAR function returns the year based on the given date in a 4-digit serial number format.
