Do you want to do this with bash? In that case this question is answered here http://stackoverflow.com/questions/6508819/convert-date-formats-in-bash — Linkan, Oct 02 '16 at 18:01

This command will have exact output you have posted at Ubuntu 16.04:

$ date -d"Sep 30, 2016 11:20:34 AM" "+%Y%m%d%H%M%S %n%u (%A)"
20160930112034

According to this question you might need to adjust it for Mac os. Check this command for ex.:

$ date -j -vJulm -v20d -v1999y '+%A'

Here is manual for date command for Mac OS X.

I am using mac osx terminal and these commands do not work some how. – Teja Oct 02 '16 at 20:34

That is _very_ likely `/bin/date` and not a bash builtin. – Dirk Eddelbuettel Oct 02 '16 at 20:37
There is no /bin/date dir on my mac osx terminal. – Teja Oct 02 '16 at 20:39
