Calculate end date base don Start date + 6 months

Hi there. Hoping this is an easy solution.

I have 2 textboxes we can call Textbox1 and Textbox2. Textbox 1 is a start date that the user enters and i would like Textbox 2 to change based on the date that is in Textbox 1. I want Textbox 2 to show an end date 6 months after the start date.

Is this possible?

I basically want to do the same thing EDate() does but in VBA

Any help is appreciated

Here is an example. Click on the cell with the date.

Thanks for he feedback!
