Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you with your concern.

You can check your warranty period, the warranty date started is when the console was purchased.

To do so, sign in to https://account.microsoft.com/devices then register your console by using the serial number.

I'm sorry but there is no video available for me to give. When you go to https://account.microsoft.com/devices then you add your console as a device using the serial number, then register you'll see the warranty start date that's when the console was purchased.
