These windows are aggregates across millions of posts — a fine place to start, and a bad place to stop. Your audience has its own clock; the numbers below get you in the room, your own data wins the room.
| Platform | Starting window (audience local time) | Notes |
|---|---|---|
| Tue–Thu 11am–1pm · Mon–Fri 6–8pm | Reels skew later in the evening; carousels do fine midday. | |
| Mon–Thu 8–11am | Pages see the best organic reach on weekday mornings. | |
| Threads | Weekdays 8–10am · 7–9pm | Conversation-driven — post when replies can snowball. |
| Tue–Thu 8–10am | B2B attention lives inside working hours; weekends are dead. | |
| Bluesky | Weekdays 9am–12pm | Early-adopter heavy; mornings in US timezones lead. |
Windows are directional aggregates, not gospel — audience geography, niche, and format all shift them. Treat the table as your first hypothesis.
Krevaya AI computes best-time suggestions from your account's own engagement history and reschedules as your audience shifts — see Calendar & Scheduling.
