How to move files older than certain time?

UNIX for Beginners Q & A
1

If there are 100 files created in a directory /data/ today from 2:00 AM to 10:00 AM

I need to move files older than 3:00 AM to a new directory /hold/

How to do that?

Also, if I have to move files between 3:00 AM to 9:00 AM, how to achieve that

Did you consider the find command? Applying the -mmin twice to enclose the desired period, or the -newer test accordingly.

How do I give the date?

find /data/ -type f -newer 11042016103500

Files are like

	1.5M (1612002)	Fri Nov 04 10:33:32 CDT 2016	887.txt 
	1.5M (1612002)	Fri Nov 04 10:33:32 CDT 2016	889.txt 
	1.6M (1652434)	Fri Nov 04 10:33:31 CDT 2016	877.txt 
	1.6M (1652434)	Fri Nov 04 10:33:31 CDT 2016	878.txt

Did you consider to read the man-page for find ?

BTW, there is no way you can reliably find out the creation date of a file. All discussions in this thread refer to the last modification time of the file (which in your case is probably sufficient).
