The man pages are your friend (man date)

This works on my system:
date -d "3 months ago"

You'll need to read the man page to understand what you're allowed to use in the date string.

That surprises me, because I showed that quite extensively in your earlier thread on this subject...

I didn't start that thread nor replied to it (or even looked at it). If I did, then I would've known

I'm very sorry about that.
I was mistaking you for the original poster.

i'm the original poster actually..
but why there's an error using the date function like
DATE=$(date -u "$1" +%Y-%m-%d) and the rest
the error is such

date: 0551-402 Invalid character in date/time specification.

i'm new in this programming language and i'm using GMT date .help me!!

Here's a little diddy I made to show date differences.

Code:

#!/bin/bash

then=`date +%B" "%d" "%Y -d "-3 months"`
recent=`date +%B" "%d" "%Y -d "-2 day"`
now=`date +%B" "%d" "%Y`
tomorrow=`date +%B" "%d" "%Y -d "1 day"`

echo " Three months ago was $then"
echo " Two days ago was $recent"
echo " Todays date is $now"
echo " Tomorrows date is $tomorrow"
