Best time to post on r/SaaS
For every hour of the week we checked what share of September 2026's posts reached the top quarter by upvotes (more than 3 upvotes). Small samples are smoothed so one lucky post can't top the list.
Best days
- Sunday27% top
- Monday25% top
- Friday24% top
Best hours (ET)
- 11 PM34% top
- 12 AM33% top
- 6 PM32% top
Best day + hour
- Thu 4 AM47% top
- Tue 9 PM44% top
- Mon 3 AM42% top
“% top” = share of posts from that time that reached the top quarter. Across the whole month it's 23%, so anything well above that did better than average.
Darker = a larger share of posts from that hour reached the month's top 25% by upvotes. Grey = fewer than 8 posts, too few to judge. Times are US Eastern.
