What our data says
Instagram: early mornings up, Saturday down
Posts published between 6 and 9 am (Paris time) got about 45% more comments than the same account’s other posts. Saturday posts got about 25% fewer. Both gaps held up in every test. The brightest cells of the grid did not: Wednesday 6 to 9 pm (160) and Monday noon to 3 pm (145) fell below average in at least one half of the period.
TikTok: Friday stands out
Videos published on Friday got about 30% more comments in their first 72 hours. The other days range from 85 to 105, within the noise. Too few accounts posted at each hour to publish a day-by-hour grid.
Facebook: watch out for Tuesday
Facebook posts published on Tuesday got about 25% fewer comments. Thursday looks strong (130) but did not hold up. Our data does not keep the hour of Facebook posts, so the study only compares days.
What it means for your posting schedule
Between 9 am and 9 pm on weekdays, the hour changes the number of comments less than most guides suggest. Avoid the dips, try an early-morning post on Instagram, and put your effort into the first hour after posting: answer the first comments and hide spam before it settles in.
Method and limits
Source: Blabla’s production data, read only, on brand accounts in Europe connected to Blabla. Instagram covers posts from 13 August to 7 November 2026, with Meta’s comment count. TikTok and Facebook cover posts from 13 October to 7 November 2026, with the comments of their first days, because comments are kept for 30 days. Ads, the brand’s own replies and accounts with fewer than 5 posts are left out.
Each post is compared with its own account: its comments are divided by that account’s average per post, capped at the 99th percentile, then averaged per account and across accounts. 100 is the account’s usual level. A cell is shown only if at least 30 accounts posted in it. It is marked solid when the gap held up when we resampled the accounts, in both halves of the period and in odd and even weeks.
Limits: the sample is mostly French and European brands and media with many comments, not creators. The window is short for TikTok and Facebook and includes the autumn holidays, Halloween and the clock change, which we handled with real time zones. Brands choose when to publish their big posts, so a cell can reflect the content more than the hour. Night slots are empty because few accounts post then. North America had too few accounts to publish.
Instagram posts with no comment at all are not stored by our sync, so the Instagram index compares posts that got at least one comment. We publish rounded ratios only, never Blabla’s absolute numbers.
Best time to post: your questions
What is the best time to post on Instagram in 2026?
In our data on European brand accounts, posts published between 6 and 9 am (Paris time) got about 45% more comments than the same account's other posts, and Saturday posts about 25% fewer. Between 9 am and 9 pm on weekdays, the hour made little difference.
What is the best day to post on TikTok?
Friday. Videos published on Friday got about 30% more comments in their first 72 hours than the same account's other videos. The other days stayed within the noise.
What is the best day to post on Facebook?
Our data shows one clear dip: posts published on Tuesday got about 25% fewer comments. Thursday looked strong but did not hold up in every test, and the hour of Facebook posts is not available in our data.
Why don't you show a best hour for every day?
Because most day-and-hour cells changed from one month to the next. We only highlight gaps that held up in every test, and we leave out cells where fewer than 30 accounts posted.
How do I find the best time for my own account?
Compare your own posts over 4 weeks: publish the same kind of content in two or three time slots, then look at comments and reach per post. In Blabla, every comment lands in one inbox with its time, so you can see when your audience talks and answer in the first hour.
