I can get the information about which os I am using by cat /etc/os-release. Which command should I use to get the release date of Raspbian OS, for example 2018-11-13. Thanks

Try 

cat /boot/issue.txt

instead. This is specific to official Raspbian image files downloaded from raspberrypi.org

All RPF Raspbian images are generated using pi-gen which adds the file /etc/rpi-issue with some information (when generated, type of image, etc).

Example:

pi@raspi3b:~/dev/tensor$ cat /etc/rpi-issue
Raspberry Pi reference 2018-04-18
Generated using pi-gen, https://github.com/RPi-Distro/pi-gen, d6c238c1b2b1b070a574d3e25048ca442e3e221f, stage5

NB: the date is the date the image is generated, not necessarily the date mentioned as the release date on the RPF website

The Answers above are both correct, but the Original Release date is not particularly meaningful; my fully updated Raspbian shows Raspberry Pi reference 2017-08-16

https://raspberrypi.stackexchange.com/a/85016/8697 shows how to list current state of the Pi.

Use uname -a and vcgencmd version to get your kernel version and bootcode build dates.
