Thank you jaslake but I need to keep it simple so that I can explain to another user if I am not there or leave the section how to and have a step by step guide (that I have already constructed). They all have the Microsoft Calendar Control. I find this way easier for me as one calendar controls the sheets and 2 calendar controls my textboxes within my Userforms. As I said, I only use 2 textboxes in a userform so that the data entry does not mix up the two and plus it's reserved only for my Userforms. Works well for me, just wanted to know a work around to use the same calendar for all (Sheets and Userforms).

Thank you all.
