HH:MM:SS, MM:SS, SS, or decimal minutes like 12.5.YouTube monetization requires 4,000 valid public watch hours over the past 12 months (plus 1,000 subscribers) — but YouTube doesn't show you a running total of hours per video. Paste your video durations here and instantly see total watch time in seconds, minutes, hours, days, and weeks, plus a progress bar against the 4,000-hour threshold. Also useful for playlist length sums and content audits.
4,000 valid public watch hours in the past 12 months, plus 1,000 subscribers (or 10M Shorts views in 90 days, plus 1,000 subscribers). This calculator helps you estimate where you stand.

Public videos that are not unlisted, not deleted, and not made for kids only. Premium subscribers' watch time also counts. Watch time on private/deleted/unlisted videos does not.
