The Twelve-Month Window Moves With You
The threshold is 4,000 valid public watch hours accumulated in the past twelve months, alongside 1,000 subscribers. Every day, hours earned more than twelve months ago drop out of the count.
For a channel publishing consistently this is invisible, because new hours arrive faster than old ones expire. For a channel that slowed down, it means the number can fall while nothing appears to be happening — and it explains the common experience of watching a dashboard number decline during a break from uploading.
The practical consequence for buying: this is not a purchase that sits and waits for you. Hours bought today start their own twelve-month clock. If you are far from 1,000 subscribers, buying hours first means burning part of that window before you can use them.
- Threshold:4,000 valid public watch hours in the past 12 months, plus 1,000 subscribers.
- Rolling:Hours older than twelve months drop out. The number can go down.
- Order second:If you are short on subscribers, get those first so the hours are not expiring while you wait.
