The included code files can be used to create a proper date picker in an Excel using VBA for a user input control. This is currently not possible in the latest verion of Excel out of the box.
This code was exported from an Excel solution posted by Siddharth Rout in StackOverflow in response to the question StackOverflow - How can I create a calendar input in VBA Excel?. I am not the original author.
I feel there is value in having the code files be made available in GitHub so that they can be forked and also Pull Requested if there is a fix that needs to be made public and distributed back to the community.
I included the original file Original File - New Calendar Ver 5.xlsm.
I make no warranties, guarantees, or other claims about the included files. Use at your own discretion and risk.
