Can we make a calendar using Pivot Tables?!?
Of course we can. Today let us learn a simple technique to create calendar style reports using Pivot tables.
Thanks to Rob for inspiration
Before making any progress, let me thank Rob from PowerPivotPro for the inspiration. Recently he wrote an article explaining how to use PowerPivot & DAX formulas to create calendar charts in Excel. I applied similar technique to Pivot tables.
Demo of Pivot Calendar
See a quick demo of pivot calendar chart before learning how to do this.
Creating a Pivot Table Calendar
Step 1: Set up an entire year of dates in a list
Lets assume, we want to make the calendar for year 2012. So write that in a cell (G3). Now, in a range of 366 cells, generate all the dates for the year (2012) using simple formulas.
- First date will be =DATE(G3,1,1)
- Next 365 dates will be previous date + 1
Step 2: Calculate Day, Month, Year and Weekday
Using DAY(), MONTH(), YEAR(), WEEKDAY() calculate the day, month, year and weekday for each of the 366 days.
Step 3: Determine the week number in a month
Now comes the tricky part. We need to find out which row each date should be displayed. First take a look at this illustration.
The logic for calculating row numbers is very simple:
- First day of a month is always in row number 1.
- If a day is not Sunday, we just use previous row number
- On Sundays, we just increment the previous row number and use it.
All of this can be expressed in a simple IF formula =IF(D7=D6,IF(F7=1,G6+1,G6),1)
- D7 contains this month, D6 is previous day’s month
- F7 contains weekday, will be 1 for Sunday and 7 for Saturday
- G6 contains previous row number (weeknum)
Step 4: Dealing with Leap years
So far we are good, except for a minor glitch. Certain years have 366 days (for example 2012) while others dont. That means, depending the year, we need to either use 365 rows or 366 rows of our data while generating the pivot report. To do this, we create a named range tblDates that refers to below formula:
=IF(Calcs!$D$3,Calcs!$B$5:$G$371,Calcs!$B$5:$G$370)
Note: D3 is TRUE when an year is leap year.
Step 5: Create pivot table that shows calendar
Now, we need to create a pivot table from the range tblDates.
Set up your pivot table like this:
Step 6: Add a slicer
To enable users to select a particular month interactively, just add a slicer on months. For this,
- Select any cell in the pivot table and go to Options Ribbon > Insert Slicer
- Select Month as field to insert a slicer.
- Adjust slicer properties to show items in 6 columns (Slicer Options Ribbon > Columns)
- Done!
At this point, you can interactively select a month & see the corresponding calendar.

Further Enhancements
Now that the basic Pivot Calendar is ready, try these ideas:
- Use a spin button / slider control to interactively adjust the year. Remember, when you do this, you need to refresh the pivot table in background using a simple macro.
- Adjust week start to Monday: Likewise, you can modify your formulas to adjust weekstart to Monday or any other day you fancy.
Using Pivot Calendar as a Chart
Of course, having a mere pivot calendar is not much fun. But you can apply this idea to create a calendar chart. See this:
Calendar Chart Demo:
How to create this Calendar chart?
To keep things simple, lets understand how to create this chart with just one metric – Employee productivity.
- Once the pivot calendar is ready, we add extra rows between each line in the calendar.
- Now, lets say, we have our employee productivity details listed by date in a table.
- Then, using lookup formulas, we fetch productivity for each day in the cell below.
- Once all the values are fetched, just select all these cells and add conditional formatting > color scale to them.
- Format the color scale settings so that you get desired colors.
- And you are done!

Do you like Pivot Calendar Idea?
I am very excited to try this out in a client project sometime soon. I think a set up like this can be used when analyzing monthly data like employee attendance, vacations, productivity, shipments, meeting schedules, project milestones etc. Since such data is represented in calendar format in real life, your audience would find calendar metaphor easy to understand. That said, any data like KPI trends, sales, visits, calls etc. should always be represented as a line /bar charts rather than calendar charts.This way, we can spot trends quickly and understand data better.
What about you? Do you like this idea? Are you planning to use a pivot calendar / calendar chart sometime in future? Please share your thoughts using comments.

Nice use of Power Query! Power Query is simply awesome! But somehow a lot of people are punishing themselves by not using it (not learning it).
An imperfect 4th approach for consideration... no codes at all...
Select myrange.
Go to Special --> Blank
Delete Cell --> Shift cell left
90% done... now we just need to move the data of 2nd column to the bottom of 1st column
Of course... Power Query is the best.
Cheers,
There is another way but it involves multiple steps:
Copy the values in column E, move the cursor to F5, Paste Special with Skip Blanks, OK
Copy the values in column D, move the cursor to F8, Paste Special with Skip Blanks, OK
And so on.
This works perfectly, albeit a little clumsily apart from the values in B17 and C16, which can be moved with simple copy and paste
Power Query Forever! I do not know how I survived for so long without knowing and using this tool, I can not recommend it to my colleagues, but by the way they prefer to suffer to learn.
My congratulations here from Brazil.
I rolled my eyes when I saw that data
Using decimal places is a nice trick to order data, thanks for that
And tweaking the first formula a bit, you can use OFFSET instead of INDIRECT
=OFFSET($A$1, MIN(IF(myrange, ROW(myrange)), ROWS(A$1:A1))-1, RIGHT(TEXT(MIN(IF(myrange, ROW(myrange) + COLUMN(myrange)*0.00001), ROWS(A$1:A1)), ".00000"), 5)-1)
Tried the above formula with the downloaded oddly shaped data file and I could not get it to work. I get #value without ctrl+shift+enter, and #ref with ctrl+shift+enter.
Sorry, it was SMALL, not MIN.
Add with CTRL+SHIFT+ENTER.
Thank you for your formula. Like the indirect formula I tested this one in older versions of EXCEL and it worked without ALTERATION in EXCEL 95. Very impressive.
Too complicated
Use =Sum to summarize all the sells to the left and Bobs Your Uncle
@Bertie... I am afraid that won't work when you have more than one value in a row.
I tested this formula in versions of Excel all the way back to Excel 95
=IF(ISERROR(INDIRECT("R"&SUBSTITUTE(TEXT(SMALL(IF(MyRange"",ROW(MyRange)+COLUMN(MyRange)*0.00001),ROWS(A$1:A9)),"00000.00000"),".","C"),FALSE)),"",(INDIRECT("R"&SUBSTITUTE(TEXT(SMALL(IF(MyRange"",ROW(MyRange)+COLUMN(MyRange)*0.00001),ROWS(A$1:A9)),"00000.00000"),".","C"),FALSE)))
So there are multiple ways of cleaning up messy data by formulas.
Wow.. Excel 95. Who knew people still use that. But as you have shown, Excel has all these beautiful and powerful functions for 23 years. It has data sciency stuff before DS was even a thing.
I had a problem with pasting the formula in the original post.
Formula should be: =IF(ISERROR(INDIRECT("R"&SUBSTITUTE(TEXT(SMALL(IF(myrange"",ROW(myrange)+COLUMN(myrange)*0.00001),ROWS(A$1:A1)),"00000.00000"),".","C"),FALSE)),"",(INDIRECT("R"&SUBSTITUTE(TEXT(SMALL(IF(myrange"",ROW(myrange)+COLUMN(myrange)*0.00001),ROWS(A$1:A1)),"00000.00000"),".","C"),FALSE)))
EXCEL even in a 16 bit version, is a very robust and capable program.
I don't like the VBA code. If you have a blank row in MyRange, the last entry in the range is doubled up in the paste.here range.
Not really. The macro is writing one cell at a time from paste.here. You have to clean the range before, which I was too lazy to write. But a line like Range(range("paste.here"), range("paste.here").end(xldown)).clearcontents should do the trick.
Adding Range(range("paste.here"), range("paste.here").end(xldown)).clearcontents fixed the problem.
for step split column by delimiter i am not getting option of split into rows or columns. Can you help me in this
Thanks Chandoo for promoting Power Query.
To simplify further, you can "Unpivot Columns" instead of right click on the newly created column and split it by comma in to rows in step 3 of Power Query.
i used
=LOOKUP(10000,B5:F5)
and got the answers. I just plagiarized this formula somewhere and use it, maybe you can explain why it works.
Regards
@Johan... I am not sure if the formula works correctly. When I tested it with the sample data in this post, it showed #N/As in two cells. Essentially, it will only give first value in each row. So if a row has multiple values, then subsequent values are missed. LOOKUP() function goes thru a list and finds the first value that is less than or equal to the input - in this case 10000 in B5:F5.
I have the need to convert pdf's to excel on occasion and they often come out a mess like this. I have used:
Cell G2 =COUNT(myrange)
Cell G3 =IFERROR(IF(G2-1<1,"",G2-1),"") copied down to G100
Cell H2 =IFERROR(LARGE(myrange,G2),"") copied down to H100
Waouw...
=IFERROR(INDIRECT("R" & SUBSTITUTE(TEXT(SMALL(IF(myrange "", ROW(myrange) + COLUMN(myrange)*0.00001),
ROWS(A$1:A1)), "00000.00000"), ".", "C"), FALSE), "")
but CTRL Shift Enter with {} before and after 🙂 😀
Here's a way with pivot table
https://www.bookkempt.com/2018/02/aligning-non-contiguous-data.html
This is brilliant. Bookmarked 🙂
Another possibility.
This assumes that you have a row index 'k' to use in the SMALL function and a column index 'h' to identify the columns of 'myRange'.
If you define 'coord' to refer to
=k+h/10 [assuming h<10]
then it will be possible to recover values later based upon location within 'myRange'. The formula 'nb' that identifies non-blanks by coordinates is given by
= SMALL( IF(myRange"", coord), k )
Finally, to unpick the pieces
= INDEX( myRange, INT(nb), 10*MOD(nb, 1) )
Whilst I am here and making trouble the PQ solution is also a tad over-complicated. All that is needed is to unpivot the entire table and remove the Attribute column.
The advanced editor would show
let
Source = Excel.CurrentWorkbook(){[Name="myRange"]}[Content],
#"Unpivoted Columns" = Table.UnpivotOtherColumns(Source, {}, "Attribute", "Value"),
#"Removed Columns" = Table.RemoveColumns(#"Unpivoted Columns",{"Attribute"})
in
#"Removed Columns"
1.fill the blank cells with 0
2.the requested column value=sum of those mess number column
but this can be used in only one column has value
Chandoo
And if we use the formula SEARCH (100000000, B5: F5)

Another approach with Power Query, it will still work if the number of columns changed:
let
Source = Excel.CurrentWorkbook(){[Name="myrange"]}[Content],
#"Added Custom" = Table.AddColumn(Source, "List", each Record.ToList(_)),
#"Removed Other Columns" = Table.SelectColumns(#"Added Custom",{"List"}),
#"Expanded LIst" = Table.ExpandListColumn(#"Removed Other Columns", "List"),
#"Filtered Rows" = Table.SelectRows(#"Expanded LIst", each ([List] null))
in
#"Filtered Rows"
Cool idea to use Record.ToList as added column. Thanks for sharing this.
Nowadays, you can just use TOCOL on Excel 2024, MS 365, and Web Excel. It has a parameter to ignore blanks/errors/both.
