Every hour Chartika checks YouTube’s list of most popular videos in each country and turns each position into points: 100 for #1, 50 for #10, down to 0 at #100. A video’s place in the chart depends on the points it collects over time, not on its lifetime view count, so a new upload that stays near the top all day can outrank an older video with far more total views.
Switch between Today, Yesterday and the last 7, 30 or 365 days to change the time window: "Today" shows what’s popular right now, while the longer periods surface videos that stayed popular for weeks or months. Combine that with a country and a chart — all videos, Music or Gaming — to zoom in on exactly the trend you’re looking for. Learn how the charts are calculated.
