Best Time to Post on Facebook on Monday
Best time to post on Facebook on Monday: 12–1 PM Eastern. Secondary window: 9–11 AM Eastern. Avoid 8 PM–10 PM — engagement is the weakest of the day.
Mondays start strong on Facebook compared to Instagram. The 9 AM – 1 PM ET window holds up well as users catch up over coffee. News and link-share content performs notably better on Monday morning than any other weekday — the "what did I miss?" dynamic. Video posts requiring sustained attention should wait for Tuesday or Wednesday.
