Gmail ID creation date is very useful in case of the recovery of forgotten password. When you forget your gmail password and you have no any option to recover your password, then you can get your gmail password in any other's mailbox by providing your id's creation date and other details. So, let me tell you how can you know the creation date of your gmail id:

> Login to your gmail id.
> Now click on the Gear icon and click Settings option.
> Now click Forwarding and POP/IMAP option.
> Under pop download section, you will see your gmail mail id creation date. Note it and keep it safe.
> Enjoy... :-)
