A live heatmap of when r/sideproject's top 100 posts of the past year were submitted. The brightest cells are the windows when this community engages most.
Analyze a different subredditBased on 100 top posts from the past year. Times in UTC.
Note: Reddit timestamps are UTC. Subtract or add your offset to convert (EST = UTC-5, PST = UTC-8). Top posts are weighted by total upvotes.
r/sideproject is built around show-and-tell posts and has consistent activity across most international time zones. The audience here actually wants to see what people are building, so timing matters less than presentation quality. Saturday and Sunday US daytime windows tend to be the most active, as the audience overlaps heavily with weekend builders. The sub's algorithm rewards posts with images, demos, or interactive elements.
Times above are UTC — the heatmap reflects the trailing 12 months of top posts, so it captures long-term patterns rather than this week's activity. Have questions about how this works? See the main tool page for FAQs.
