One of the popular uses of Excel is to maintain a list of events, appointments or other calendar related stuff. While Excel shines easily when you want to log this data, it has no quick way to visualize this information. But we can use little creativity, conditional formatting, few formulas & 3 lines of VBA code to create a slick, interactive calendar in Excel. Today, lets understand how to do this.
But first, a reminder to join my Advanced Excel masterclass in USA
As you may know, I am running my first ever Advanced Excel & Dashboards Masterclass in USA this summer (May / June 2013). We will be doing 2 day interactive sessions on Excel, advanced Excel, interactive charts, pivot tables & dashboards in Chicago, New York, Washington (DC) & Columbus (OH). If you live near any of these cities and want to become awesome in Excel, please consider enrolling in my Masterclass.

Back to the interactive calendar
Coming back to our topic at hand – interactive calendar, what do we mean by this?
Well, something like below:
How to create an interactive calendar from a set of events
1. Collect all the event data in a table
Just enter event data in a table like below:
2. Set up a calendar in a separate rate
If your events span several months, then you can use formulas to generate calendar.
In my case, all the events (Masterclass sessions) are in May & June 2013. So I just entered date of May 1st in a cell, dragged it sideways and then re-arranged the cells to make it look like a calendar. At this stage, the calendar should look like this:
3. Name the calendar range
This is simple. Select all the cells in calendar range and give a name to it. I called mine “calendar”.
4. Assign a cell for identifying which date is selected
Select a blank cell in your workbook, give it a name like “selectedCell”. We will use this to identify which date is selected by user.
5. Write Worksheet_selectionchange() event
This will help us identify when user selects a cell in “calendar” range. The below 3 line VBA should do. Please attach it to the sheet where your calendar is.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Application.Intersect(Target, Range("calendar")) Is Nothing Then
[selectedCell] = ActiveCell.Value
End If
End Sub
Tutorial: Showing details when user selects a cell
6. Set up the formulas to show details when a valid date is selected
Lets say, each event has 4 details associated with it – title, date, venue & description.
Now, we need to show details of the event when user selects a date in the calendar. Since the selected date is in “selectedCell”, we can use VLOOKUP, IF, IFERROR formulas to do this:
- Fetch event title in a cell if date selected has an event in it. Else keep it blank
-
=IFERROR(VLOOKUP(selectedCell, table_of_events, event_title_column, false),"")
-
- Fetch rest of event details, but keep them blank if date has no events.
Lets say these 4 details are fetched to cells D1, D2, D3 & D4 cells.
7. In calendar sheet, add 4 text boxes and assign them to cells
Finally, in calendar sheet, add 4 text boxes. Assign them to D1, D2, D3 & D4 cells. Arrange and format them as you fancy.
Tip: to assign a cell to text box, just select the text box, go to formula bar and type =D1 press enter.
8. Set up conditional formatting to highlight selected dates
Finally, add a simple conditional formatting rule to highlight the selected dates in calendar. This is simple. Assuming calendar starts at cell A1,
- Select the calendar range
- Go to conditional formatting
- Add new rule
- Select rule type as “Use a formula to determine which cells to highlight”
- type the rule as =A1=selectedCell
- Set up formatting
PS: in my data above, I have used different formula as we need to highlight 2 dates of a Masterclass even when 1 is selected.
Tip: Introduction to conditional formatting.
9. Clean up and formatting
Clean up your worksheets and format the calendar so that it looks gorgeous. And you are done!

Examine the formulas in “Calcs” sheet & VBA code so that you can see how this is weaved.
Work with calendar data often, then you are in luck
If you use calendar data often and are looking for some inspiration, ideas & examples on how to represent it, then check out below examples:
- Employee vacation tracker & dashboard
- Creating perpetual calendar & event tracker in Excel
- Interactive pivot table calendar & chart in Excel
- Creating an interactive picture calendar
- Employee shift calendar template
- Annual goals tracker
Do you like the interactive calendar?
I often use interactive calendars in my dashboards & client projects. Since calendars are very natural way to understand events, they work really well.
What about you? Do you use calendars often? How do you like the above technique? Please share your thoughts & ideas using comments.

Some great contributions here.
Gotta love the Friday 13th formula 😀
Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂
(BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )
Great compilation Chandoo
For the "Clean your text before you lookup"
=VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)
I would like to share a method to convert a number-stored-as-text before you lookup:
=VLOOKUP(E20+0,F5:G18,2,0)
@Peder, yeah, I loved that formula
@Aires: Sorry, I misunderstood your formula. Corrected the heading now.
@John.. that is a cool tip.
Hey Chandoo,
That p-value formula is really great for a statistics person like me.
What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.
You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)
Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.
Week1 Week2
10 11
12 9
9 10
7 8
5 8
Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK
In the Variable 1 Box, select the range of data for week 1.
In the Variable 2 Box, select the range of data for week 2.
Check "Labels"
In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.
.05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.
Select a range output.
Excel calculates a number of results: Average (mean) for each week's data, etc.
You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.
So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.
Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!
Thanks!
Eric~
Fantastic stuf..One line explanation is cool.
Thanks to all the contributors
OS
Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")
I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)
Extract the month from a date
The easiest formula for this is =MONTH(a1)
It will return a 1 for January, 2 for February etc.
if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u
@Anjali
If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2
If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
kindly share with me new forumulas.
