How to find out when my gmail account was created?

I was trying to find out when my gmail account was created and i found following soloution on google product forum.shared by Paviraad.

There is another way to find out the account creation date.

 Goto Gmail Settings --> Forwading and POP/IMAP.

In the POP Download section there will be 1. Status: POP is enabled for all mail that has arrived since xx/xx/xx.

Hopefully this will be it if you have not changed your POP setting after the account creation.
