Adding a calendar to your sheet can make it easy for you to keep track of your schedule. While inserting such element isn’t readily available in the program, you can run an Excel macro named, CalendarMaker to insert a calendar in Excel.
To run the macro, if you haven’t already, enable the Developer tab. From the developer tab, you will then have to insert a module to enter the code for the CalendarMaker macro. We will be breaking the method to embed a calendar in Excel down step-by-step in this article, so keep reading!
Step 1: Insert a Module in VBA Editor
For this step, we will be using the Visual Basic Editor to enter the code for our macro.
- Head to the Developer tab.
- From the Code section, select Visual Basic.
- Right-click on ThisWorkbook from the sidebar.
- Select Insert > Module.
Step 2: Enter the Code for the Macro
Once you insert the module, you can insert the code on the right. We will be using a simple Visual Basic procedure from the official Microsft website.

Copy-paste the following code into the window:
Sub CalendarMaker()
' Unprotect sheet if had previous calendar to prevent error.
ActiveSheet.Protect DrawingObjects:=False, Contents:=False, _
Scenarios:=False
' Prevent screen flashing while drawing calendar.
Application.ScreenUpdating = False
' Set up error trapping.
On Error GoTo MyErrorTrap
' Clear area a1:g14 including any previous calendar.
Range("a1:g14").Clear
' Use InputBox to get desired month and year and set variable
' MyInput.
MyInput = InputBox("Type in Month and year for Calendar ")
' Allow user to end macro with Cancel in InputBox.
If MyInput = "" Then Exit Sub
' Get the date value of the beginning of inputted month.
StartDay = DateValue(MyInput)
' Check if valid date but not the first of the month
' -- if so, reset StartDay to first day of month.
If Day(StartDay) <> 1 Then
StartDay = DateValue(Month(StartDay) & "/1/" & _
Year(StartDay))
End If

' variables.

& " (or use 3 letter abbreviation)" _
& Chr(13) & "and 4 digits for the Year"
MyInput = InputBox("Type in Month and year for Calendar")
If MyInput = "" Then Exit Sub
Resume
End Sub
Step 3: Run the Macro in Your Worksheet
After you’ve entered the code, you can run the code as a macro. The macro will ask you to enter the name of the month and the year you wish to enter a calendar for.
- Go to the Developer tab and select Macro from the Code section.
- Select CalendarMaker under the Macro name section.
- Click on the Run button.
- Type the name of the Month and the Year in the pop-up. For example, if you want to enter the calendar for January of the year 2023, I will enter “January 2023” in this section.
- Click OK.
After you insert the calendar, Excel automatically protects your sheet. This means you cannot make changes to your worksheet.To edit your document, unprotect your sheet from the Review tab in the menubar.
