| Mon to Thu around noon. Tue and Wed run to 8 PM. | Sprout Social (2026) | |
| Threads | Weekday mornings, 6 to 11 AM. Thu 9 AM tops the list. Evenings (6 to 11 PM) did worst in the same study. Fewer studies cover Threads, so the exact hours are less certain. | Buffer (2.5M posts, 2026) |
| Weekday mornings, around 10 AM. Wed 8 AM to 1 PM is the widest window. | Sprout Social (2026) |
