Date issue

How to compare two input date string?

What I am basically trying to get here is get file names in a directory for a particular date range.
I would like to get the file data growth over a certain period of time.

When below code ran I am getting error - -sh: 20190929: No such file or directory

Any better tuned code would be helpful.
Code:
unset next_date
unset curr_date
next_date=20190101
curr_date=`date +%Y%m%d`
counter=0
while (  $next_date < $curr_date );
do
date_from=$(date -d "$next_date +$counter days" '+%Y%m%d')
echo $date_from
echo ">>>>>"$counter
((counter+=10))
echo $counter
date_to=$(date -d "$next_date +$counter days" '+%Y%m%d')
echo $date_to
#ls -lrt $(find /home/test/ -type f -newermt $date_from \! -newermt $date_to ) ## list files for specific range 
done

DATETIME.__CONSTRUCT(3) 						 1						   DATETIME.__CONSTRUCT(3)

DateTime::__construct - Returns new DateTime object

       Object oriented style

SYNOPSIS
public DateTime::__construct NULL ([string $time = "now"], [DateTimeZone $timezone]) DESCRIPTION
Procedural style DateTime date_create NULL ([string $time = "now"], [DateTimeZone $timezone]) Returns new DateTime object. PARAMETERS
o $time -A date/time string. Valid formats are explained in Date and Time Formats. Enter NULL here to obtain the current time when using the $timezone parameter. o $timezone - A DateTimeZone object representing the timezone of $time. If $timezone is omitted, the current timezone will be used. Note The $timezone parameter and the current timezone are ignored when the $time parameter either is a UNIX timestamp (e.g. @946684800) or specifies a timezone (e.g. 2010-01-28T15:00:00+02:00). RETURN VALUES
Returns a new DateTime instance. Procedural style returns FALSE on failure. ERRORS
/EXCEPTIONS Emits Exception in case of an error. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.3.0 | | | | | | | If $time contains an invalid date/time format, | | | then an exception is now thrown. Previously an | | | error was emitted. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 DateTime.__construct(3) example Object oriented style <?php try { $date = new DateTime('2000-01-01'); } catch (Exception $e) { echo $e->getMessage(); exit(1); } echo $date->format('Y-m-d'); ?> Procedural style <?php $date = date_create('2000-01-01'); if (!$date) { $e = date_get_last_errors(); foreach ($e['errors'] as $error) { echo "$error "; } exit(1); } echo date_format($date, 'Y-m-d'); ?> The above examples will output: 2000-01-01 Example #2 Intricacies of DateTime.__construct(3) <?php // Specified date/time in your computer's time zone. $date = new DateTime('2000-01-01'); echo $date->format('Y-m-d H:i:sP') . " "; // Specified date/time in the specified time zone. $date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru')); echo $date->format('Y-m-d H:i:sP') . " "; // Current date/time in your computer's time zone. $date = new DateTime(); echo $date->format('Y-m-d H:i:sP') . " "; // Current date/time in the specified time zone. $date = new DateTime(null, new DateTimeZone('Pacific/Nauru')); echo $date->format('Y-m-d H:i:sP') . " "; // Using a UNIX timestamp. Notice the result is in the UTC time zone. $date = new DateTime('@946684800'); echo $date->format('Y-m-d H:i:sP') . " "; // Non-existent values roll over. $date = new DateTime('2000-02-30'); echo $date->format('Y-m-d H:i:sP') . " "; ?> The above example will output something similar to: 2000-01-01 00:00:00-05:00 2000-01-01 00:00:00+12:00 2010-04-24 10:24:16-04:00 2010-04-25 02:24:16+12:00 2000-01-01 00:00:00+00:00 2000-03-01 00:00:00-05:00 SEE ALSO
