How to know the current quarter with date?

Question

Is it possible to know the current quarter using Linux command line?

I didn\'t find a way to do it within the date man page.

Answer 1

There is now the %q format to show this information.

From the coreutils-8.26 release log from November 30, 2016:

New Features
...
date now accepts the %q format to output the quarter of the year.

And yes it works!

$ date "+%q"
4
$ date "+%Y%q"
