Your Tier activity period is based on the last date you earned at least 1 GigPoint.
Every time you earn GigPoints, your activity period automatically extends for another 365 days from that date.
This means your Tier activity is based on your individual earning activity rather than a fixed calendar year.
Example: If you earn GigPoints on October 15, your activity period will extend for another 365 days starting from October 15.
