5 Ways To Find Week Of Month In Excel

Determining the week of the month can be a useful tool in various Excel applications, such as financial planning, project management, and data analysis. While Excel doesn't have a built-in function to calculate the week of the month, there are several workarounds that you can use to achieve this. In this article, we will explore five ways to find the week of the month in Excel.

Understanding the Concept of Week of Month

Before we dive into the methods, it's essential to understand the concept of week of month. The week of month is a way to divide a month into weeks, with the first week starting on the first day of the month. For example, if the month starts on a Sunday, the first week will be from Sunday to Saturday.

Method 1: Using the WEEKDAY Function

One way to find the week of the month is by using the WEEKDAY function in combination with the DAY function. The WEEKDAY function returns the day of the week (1-7) for a given date, while the DAY function returns the day of the month (1-31).

Here's the formula:

=INT((DAY(A1)-WEEKDAY(A1))/7)+1

Assuming the date is in cell A1.

Method 2: Using the ISO_WEEK Function

Another way to find the week of the month is by using the ISO_WEEK function, which returns the ISO week number for a given date.

Here's the formula:

=ISO_WEEK(A1)-ISO_WEEK(DATE(YEAR(A1),MONTH(A1),1))+1

Assuming the date is in cell A1.

Method 3: Using a User-Defined Function (UDF)

If you're comfortable with VBA, you can create a user-defined function (UDF) to calculate the week of the month.

Here's an example UDF:

Function WeekOfMonth(date As Date) As Integer
  WeekOfMonth = Int((Day(date) - Weekday(date)) / 7) + 1
End Function

You can then use this UDF in your Excel worksheet:

=WeekOfMonth(A1)

Assuming the date is in cell A1.

Method 4: Using a Formula with the DATE Function

Another way to find the week of the month is by using a formula with the DATE function, which returns a date value for a given year, month, and day.

Here's the formula:

=INT((DAY(A1)-DATE(YEAR(A1),MONTH(A1),1))/7)+1

Assuming the date is in cell A1.

Method 5: Using a Formula with the TEXT Function

Finally, you can use a formula with the TEXT function to find the week of the month.

Here's the formula:

=INT((DAY(A1)-TEXT(A1,"mmm")*1)/7)+1

Assuming the date is in cell A1.
