Date Picker - Validation to only allow workdays

[JustHooch]

Hello,

I have a User Form with a DatePicker. I want to Add validation so that only future workdays can be selected (excluding both weekends and Holidays).

• Date Picker name = DTPickerLaunch
• Validation occurs on command: Private Sub CommandButtonContinue_Click()
• List of Holidays is located at 'Dropdown Values'!$J$19:$J$48

DTPickerLaunch currently defaults to today's date. I got as far as to validate that the field is changed but that was it. My code for the Command button is below.

Can someone help me to update the validation with the above criteria?

'When Click Continue from main page
Private Sub CommandButtonContinue_Click()
