I have need to find the day of the week es. monday tuesday Wednesday etc… with commandos dos

Under Windows XP Pro the day of week is part of the output from date /T however if you are running XP home the easiest choice is to use a tiny utility I coded and can send you if you contact me by a private message with your e-mail address.

In this command... Set DOW=%Date:~-14,3% echo %DOW% You are copying the characters from the right -14 character. This set the pointer to where you want to start copying. The 3 sets how many characters you want to copy. So the full %Date% looks like.... Wed 10/28/2009 -14,1 = W -13,1 = e -12,1 = d -11,1 = -10,1 = 1 -9,1 = 0 -8,1 = / -7,1 = 2 -6,1 = 8 -5,1 = / -4,1 = 2 -3,1 = 0 -2,1 = 0 -1,1 = 9
