Mornings, before the working day takes over
Buffer, Hootsuite and Metricool all name 9:00, and Buffer's 14 million Facebook posts do best between 6:00 and 11:00 on weekdays. Afternoons, 12:00 to 17:00, are Buffer's weakest stretch.
Buffer finds one exception: on Mondays, posts between 19:00 and 22:00 beat the morning.
Tuesday and Wednesday lead, weekends trail
Tuesday and Wednesday are each named by 2 of 4 studies, and no study ranks a weekend day among Facebook's best. Buffer's weakest day is Saturday, Metricool's is Sunday.
Why Sprout says afternoon
Sprout measures when reactions and comments happen, not when the post went out. A post at 9:00 keeps collecting through the day, so the two answers fit together: publish in the morning, and expect the engagement to run into the afternoon.
Metricool's Facebook page uses its 2025 data, and its main guide gives 12:00 to 14:00 on Monday and Wednesday instead. That makes 9:00 the safer start.

Sources and method
Every window in this guide is what a study's own page says, read on the date beside it. Where a study's overview and its page for one platform disagree, we used the platform page, which is newer and narrower.
The charts count how many of the studies name each hour or day. They show where the studies agree, not how much engagement an hour gets: no study publishes its raw numbers.
