Count Dates in Given Year
Assuming that you have a list of data in range B1:B6 that contain date values, and you want to count those dates by a specified year(2018), how to achieve it. or you want to count the dates by a specified month (5).
You can create a formula based on the SUMPRODUCT function and the YEAR function to count dates by a give year. Just like this:
=SUMPRODUCT(1*(YEAR(B1:B6)=2018))
Type this formula into a blank cell and then press Enter key to apply this formula.
The count number is calculated by this formula in Cell C1.
You can also use another excel array formula based on the SUM function , the IF function and the YEAR function to achieve the same result.
=SUM(IF(YEAR(B1:B6)=2018,1))
The Year function will convert the data value to a year value only. and the IF function will check if the year value returned by the YEAR function is equal to the given year, if so, return value 1. otherwise, returns nothing. and the sum function will sum the array list that returned by the IF function.
You need to type this formula into a cell, and then press Ctrl + Shift + Enter keys in your keyboard to convert this formula as a array formula.
Count Dates in a given Month
To count dates in a given month, you can create a formula based on the SUMPRODUCT function and the Month function. For example, you want to count datas in range of cells B1:B6 by a given month value 5. you can write down this formula:
=SUMPRODUCT(1*(MONTH(B1:B6)=5))
Or you can also write down an excel array formula based on the SUM function, the IF function and the MONTH function. Just like this:
=SUM(IF(MONTH(B1:B6)=5,1))
Count dates in a given date(year,month, day)
If you want to count the number of a give date (9/7/2018) in a range of cells (B1:B6) in Excel, You can use a formula based on the COUNTIF function. Just like this:
=COUNTIF(B1:B6,"9/7/2018")
Count Cells between Dates
If you want to count the number of cells that contain dates between two specified dates, You can still use the COUNTIFS function to create a formula to achieve the result.
For example, you want to count the number of cells that fall between two dates(from 1/1/2017 to 10/1/2018), and you can use a fromula based on the countif function. Like this:
=COUNTIFS(B1:B6,">"&"1/1/2017",B1:B6,"<"&"10/1/2018")
