Date saved from userform to cell in US form. How to force save it in UK form?

I have the below code set which saves calculation on a excel sheet but when the dates are saved, they are saved in US format (MM,DD,YYYY). I want to save the dates in UK format on the sheet from the following text boxes: txtFirstReadDate, txtSecondReadDate, txtRequiredDate.

Thank you
