Excel Formula To Find Week Of Month Easily
Determining the week of the month can be a useful calculation in various contexts, such as finance, HR, or project management. However, unlike calculating the week of the year, which has a straightforward formula, finding the week of the month requires a bit more effort. Fortunately, there's a neat Excel formula to make this task easier.
Understanding the Concept
Before diving into the formula, it's essential to understand how the week of the month is calculated. The week of the month is typically determined by the day of the month. For instance, if the date is between the 1st and 7th, it's considered the first week of the month. If it's between the 8th and 14th, it's the second week, and so on.
The Formula
To calculate the week of the month in Excel, you can use the following formula:
=INT((DAY(A1)-1)/7)+1
Where:
A1is the cell containing the date you want to calculate the week of the month for.DAY(A1)returns the day of the month (1-31).(DAY(A1)-1)subtracts 1 from the day of the month, effectively making the first day of the month (1) equivalent to 0./7divides the result by 7, which is the number of days in a week.INT()rounds down to the nearest whole number, effectively giving us the week number.+1adds 1 to the result, since the first week of the month should be 1, not 0.
Example Usage
Suppose you have a date in cell A1, and you want to calculate the week of the month in cell B1. Enter the formula =INT((DAY(A1)-1)/7)+1 in cell B1, and press Enter.
Alternative Formula
If you prefer a more concise formula, you can use the following:
=WEEKNUM(A1, 2)-WEEKNUM(DATE(YEAR(A1), MONTH(A1), 1), 2)+1
Where:
WEEKNUM(A1, 2)returns the week number of the year for the date in cell A1, using the ISO 8601 standard (Monday as the first day of the week).DATE(YEAR(A1), MONTH(A1), 1)returns the first day of the month.WEEKNUM(DATE(YEAR(A1), MONTH(A1), 1), 2)returns the week number of the year for the first day of the month.-subtracts the week number of the first day of the month from the week number of the date, effectively giving us the week number of the month.+1adds 1 to the result, since the first week of the month should be 1, not 0.
Comparison of Formulas
Both formulas will give you the correct week of the month. However, the first formula is more straightforward and easier to understand, while the second formula is more concise and might be preferred by those who are familiar with the WEEKNUM function.
