Your tenure is calculated by the amount of time you've had a gold membership. Prior to this, it was calculated simply by how long you've had the account from start to end. This has changed now, and if you notice a change in your tenure it's more than likely
because you've only had a gold membership for that amount of time.
For Example: You could have started a Xbox LIVE account back in 2006 and up until the recent changes to how tenure is calculated you would have had a tenure of 7 years. However, since it's now changed, let's say you only had a paid Xbox LIVE Gold membership
for 3 of those years and the rest of the time your account stayed dormant or inactive without a paid membership. Your new tenure would only display the time you paid for your Gold membership, and that would be 3.
Tenure is calculated by full years, not months. So if you use the example I gave, and you're on your 3rd year and have added a 12 Month Gold subscription to your account, when a full 12 months of Gold time passes by you get another year added to your tenure.
So the example number would go from 3 to 4.
You should be able to see how many years you've had an active gold membership by going through your subscription history found
here. If you're having trouble doing that, I'm sure a forum support agent can take a look for you when they see the post.
