Using dates in a batch file

Main part of this batch is done in the first three lines beginning with the command SET. We will analyze further first line:. Now we need just part of this output the date string for out variable named DAY. Also, we counted position of that information. We will now do the trick. The x and y are number position and length. We will indicate position of first character with value of X. In our example, this is 7. With second value we will indicate length of the substring.

In our example that will return We do the same for a month and the year. Eventually we have three new variables for every element of the today date. We can do that with following command:. We just need to write other variables one behind other and the batch interpreter will collect concatenate their values in one unique string.

In our example, we collected 27 th day of the 5 th month of the year in the string with value of Our demo batch file is just printed this on the screen with ECHO command.

I am in need of a way to get the full 24 hr time displayed live. I am looking for a way to make that happen automatically without me hitting enter constantly.

Thanks in advance! Thank you very much Srini for this tutorial.
