How to create a folder with name as current date in batch (.bat) files

Question

I don\'t know much about windows .bat file syntax. My simple requirement is to create a folder at a specific location with name as current date. I tried searching this on go

Answer 1

I needed both the date and time and used:

mkdir %date%-%time:~0,2%.%time:~3,2%.%time:~6,2%

Which created a folder that looked like: 2018-10-23-17.18.34

The time had to be concatenated because it contained : which is not allowed on Windows.
