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.

21 Responses to “Distinct count in Excel pivot tables”
The distinct count option works well but I have found that if I have a date field and want to group by year, month, etc. that option seems to be disabled. I need to do both, distinct count and group by year/month.
Example data; sales orders with item quantities with dates.
Challenge; sum the item quantities, count the distinct orders and group by month. How do I do this?
Perhaps that's not possible due to the grouping?
@Al... When you use data model based pivots, you cannot group values manually anymore. Why not use Excel 2016's default date grouping option? In this case we have just a few dates, so Excel is not grouping them, but if you have an year's worth of data, when you make the pivot with date in the row label area, Excel automatically groups them. If you have fewer dates or want to use your own grouping, just create a table with all dates, add columns with month, week, year etc. Then connect this table (these types of tables are usually called as calendar tables) to your data on date field as a relationship. Now you can create reports by month, quarter etc easily.
Is this the only way to do it in 2013? I find it rather cumbersome to have to create another data table listing dates with the another column for MONTH() and YEAR() to be able to summarise data for senior level...
I know people find adding calendar tables cumbersome, but it is a best practice and let's you add more layers of analysis quite easily. For example, adding analysis by weekday vs. weekend or by financial quarter or YTD calculations (you would need either Power Pivot DAX or some very carefully setup pivot table value field settings)
I had absolutely no idea this was possible. Very useful, nice work!
Doesn't work for 2010 version though (or at least not my works version)
Hi ,
The post has the following in it :
These instructions work only in Excel 2016, Office 365 and Excel 2013.
when i have 2 different Pivot tables, one without the enabled “Add this data to data model” option, and the other one with it enabled.. is there anyway i can link slicers between them?
if the answer is NO,, what to do ?
Quick note, the “Add this data to data model” option is not available for the Mac version.
perhaps outside scope of this article but I have found when I attempt to create a pivot table from an external data source (connection to a sql view) the "Add this data to data model" becomes greyed out. Anybody experienced and found a solution so I can start getting distinct count in my pivot tables?
Is there a way to still add a calculated field when using distinct count?
I found I can't change the date source after tick the " add this data to the data model", can you help to adv how to change the date source in such case?
Is there a way to update the source once you have added to the data model? I receive a new spreadsheet weekly and would like to update the connection so my tables pull from the new source.
Hi Crhis, I like how you have hulk (superhero) as your avatar. Do you know that there is a superhero in Excel too? It's Power Query. You can use it to solve your problem in a simple click. Here an intro if you need some guidance.
Powerful Introduction to Power Query
A big Thank you. It worked.
Hi, have survey data that I need to analyze but the challenge is that my key fields are showing horizontally. I tried to transpose the fields using Power Query, but unfortunately the new fields are returning same values on a pivot table despite using distinct values
How I can a do a pivot table with discount conts in some columns and then generate shor report filter pages. pls it drives crazy
Hi. Why grand total pivot of distinct count is 13? shouldn't it be 67?
Great Answer! Saved me lots of time!
Thank you!!!
Worked awesome! Thanks!!
Hi Chandoo,
I am using pivot tables for distinct count and now I need to update them with new set of data. But when I update the source data, all the columns and formatting of Pivot table disappears and I need to build it from Scratch.
Is there a possibility that I can update the source data with new rows added and also retain my pivot tables?
