How to Pop-up Calendar in any cell. My excel is 2016 and my System is a x64-Based PC

Hello dear profesionals.
I would like to have the funtion to click in a specific cell in excell and a calendar pop-up. My excel is 2016 and my system type is a x64-Bsed PC.
I am trying to have a calendar pop-up when I click in a specific cell in my excell spreadsheet. I have two cells, on for DATE in B4 (where I want to add the option to click in that cell and a calendar pup-up). And another cell (D4) with time and I would like to have the option to set-up a time as well. See my attachment in case you want to see the form.

Thanks for your contribution to this wonderful forum. I hope to hear from you soon.

Hi Alan, Thank you very much, but when I try to add the code to my file it does not work. I really would rather to learn how to do it and I will apply the learning lesson in any other spreadsheet. Let say, if I would like to pup-up a calendar in a B6 cell, How could I do it for this specific Cell (B6)?

Thanks for you time Alana on this. I hope you could help me on this.
