Quick answer
Peak window · Sunday · audience local time
The best time to post on Facebook on Sunday is 9–11 AM, with 7–8 PM as backup windows — in your audience's local time.
Sunday is Facebook's weakest day, with a modest morning window and a small pre-Monday evening bump. Community-style content — recaps, thank-yous, week-ahead notes — fits the mood best.
Sunday tip
If you post on Sunday, make it warm and communal rather than promotional: a week recap or a thank-you to customers sets up Monday's content nicely.
What to post on Facebook on a Sunday
Knowing the window is half the job — the other half is having something that fits the day's mood. Sundays on Facebook reward a particular kind of content, and these three formats are reliable starting points. Treat them as repeatable series rather than one-offs: a format that returns every Sunday gives your audience something to expect, and gives you one less decision to make.
The warm week recap
What happened, who made it good, what you're grateful for. Sunday's quiet feed suits community warmth better than any promotion.
A next-week preview
One thing to look forward to. It gives Monday's practical post a head start and catches the small pre-week evening bump around 7–8 PM.
A quiet evening question
"What's one thing you're cooking this week?" Sunday-evening browsers answer easy, cosy questions — and the comments carry into Monday's feed.

Why these windows work
Facebook's feed heavily favours posts that spark conversation — comments and shares weigh far more than reactions. Posting when your audience is online maximises early comments, which is the single strongest signal for further distribution. Question-style and conversation-starting posts amplify the timing effect.
As always: these windows aggregate published engagement studies and are a starting point — see the full sources & methodology on the Facebook overview. Once you have a few weeks of posting data, your own audience analytics are the better guide.
Preguntas frecuentes
Is it worth posting on Facebook on Sundays at all?
For most business pages, only to maintain a daily cadence. If you post 3–5 times a week, spend those slots Tuesday–Friday instead.
What about Sunday evening — does the pre-week bump help?
There's a small lift around 7–8 PM, but it's far weaker than Instagram's or TikTok's Sunday-evening peaks. Treat it as a bonus window, not a strategy.
