![]() =SUMPRODUCT( (WEEKNUM(Table13]) *Table13 ) Since SUMPRODUCT function comfortably handles arrays, we can use this array of week numbers to create a summary as shown below. The above function does not return an error but an array of week numbers from the given dates range. It can be forced to accept range by adding zero to a range i.e. It is not entirely true that WEEKNUM does not accept a range argument. Since WEEKNUM does not accept a range argument, then we have to create a helper column so that we can be able to use SUMIF Given the below data, Show totals per week. In this article, I will show you 3 ways to simplify your weekly analysis: So, How do you get week numbers in an array given a range of dates?ĭo you need to always use a helper column to convert dates to week numbers before any analysis is done? =WEEKNUM(K11:K110) just returns #VALUE! error. NB: If the return type is omitted, function defaults to week start on Sunday all the way to Saturday =WEEKNUM( serial_number, ) īeautiful as the function is, it has one major weakness, WEEKNUM doesn’t accept a range argument e.g. This is mostly so when you are in the production section.Įxcel has a beautiful but overlooked function ( WEEKNUM) that returns an integer representing the week in the year (1 to 53).įor anyone not familiar with WEEKNUM function, it contains 2 arguments Serial_number ( the date to return the week number for) and an optional Return_type (an integer that defines when the week starts). Make sure to download the accompanying spreadsheet so you can see this in action.Every organization requires weekly summaries to monitor peak and off-peak periods. The main thing is to remember that the number that is output for a given day can be changed you should not blindly trust the output of this function if it was created by someone other than yourself. I almost always put a 2 in for the return_type argument for the WEEKDAY function because it just seems to make more sense that the first day of the regular work week should be 1. Type a comma to go to the next argument and then type a number for the corresponding option or select it from the drop-down menu that appears:īy putting a 2 in for the second argument, you can see that Sunday is now the 7th day of the week for this calculation.Select the cell that contains the date:.This is almost exactly the same as the above example except that we now use the second argument. Return the Day of the Week with Different Starting Numbers Look to the example below to change which day starts the week. Make sure you have a cell with a date in it.īy default, Sunday is the first day of the week.Numbers 1 (Thursday) through 7 (Wednesday). Numbers 1 (Wednesday) through 7 (Tuesday). Behaves like previous versions of Microsoft Excel. There are 10 different values that can be entered for the return_type argument. Return_type Arguments for the WEEKDAY Function Look below for a full list of options for this argument. If you put a 2 in for this argument, Monday will be 1 and Sunday will be 7. If you leave this argument empty, Sunday will be 1 and Monday will be 2 etc. This argument tells the function how to number the days of the week. If you want, you can also enter the date by hand using the DATE() function, but that is almost never recommended as it makes the spreadsheet harder to use and maintain. You simply need to reference a cell that contains a date for this argument to work. This is the date that you want to use for the calculation. ![]()
