How many more days do I have on my Xbox gold membership

You can check by going to your Microsoft account -> Services & Subscriptions -> Check under "Xbox Live Gold" and it should tell you when the next charge is/how long until it will expire. I believe you can also check within the subscriptions tab on the
system itself.

It will take a few days to update. How many varies for each person. Why? I am unsure, that's just how the system works. Also, you will not be eligible for Xbox LIVE Rewards from things such as Xbox LIVE Gold Membership trial codes and Free Gold Weekends.
The only way you can become eligible is by purchasing/activating a gold membership.

I answered this to the best of my abilities.

Hope this helped,

That is correct it is how many years you have had a xbox live gold membership.

Think many people have this problem.. i ask myself is there any compensation? Because my membership goes on and on and i cannot use it? And thats not my fault...example: gold members pay for 3 months and can't use it, lets say 1 day.. So I think Microsoft
should give us one more day Gold membership, for every day they have such big problems. Cause i pay for that, and can't use it, because of MC's networkproblems..

Sry for my english but i think you should understand the point xD

I also think it is weird how it started the day after I renew my xbox live gold membership
