Date function in vbscript

[ashishap]

I am a student and novice to programming
I am stuck up with the code for date function in vbscript
A user has to put in his own date & display the day for that date in the msgbox.
I got the code for the system date but what if the user wants to put his custom date & get it in the msgbox.

You can use a prompt as user input, or just a regular input tag as well. What more are you trying to do?
