Best time to post on social media: what the research says and how to find yours

Let us begin with evidence we can actually point to. HubSpot publishes a regularly updated article titled The Best Times to Post on Social Media in 2025, last updated in March 2025 at the time we checked. According to HubSpot, the best times differ by network. For Instagram it suggests Fridays as the peak day, with early mornings of roughly 7 to 9 a.m. and early afternoons working best on weekdays, and it advises avoiding Sundays and the hours around midnight. For Facebook it suggests similar guidance but slightly later mornings, around 9 to 10 a.m., and recommends avoiding weekends.

For LinkedIn, HubSpot says to avoid Saturdays, Sundays and Mondays, with 10 a.m. through noon on weekdays considered peak. For Pinterest it suggests Fridays, Tuesdays and Thursdays in the late afternoon and early evening. For YouTube it suggests Friday afternoons or the 9 to 12 window on weekends. For X it says you can post more often and worry less about strict windows, favoring late morning and early afternoon on weekdays. And for TikTok it is candid that recommendations vary, suggesting you experiment with early-week mornings, weekday afternoons and Sunday evenings.

Read that summary the way HubSpot itself frames it. The article compiles findings from several published studies and expert comments, so it is a roundup of what others report, not a single measurement of your audience. HubSpot also tells readers to tailor the approach to their own followers, and one expert it quotes puts it well: “The best data you can use is your own.” We agree completely. Use these windows as the first slots you try, write them down, and expect to replace them once you have numbers from your own accounts.

If a single best time existed, the published sources would agree, and they plainly do not. The HubSpot roundup alone points to mornings for Instagram and Facebook, mid-morning to noon for LinkedIn, late afternoon and evening for Pinterest, and afternoons or weekends for YouTube. Those differences are not accidents. They reflect how people use each network. LinkedIn is browsed largely during the working day, Pinterest is a planning and search tool used in leisure moments, and YouTube is often watched in longer sessions when people have free time. The same hour means something different on each.

Audience is the second reason. A time zone offset of a few hours can move your best slot completely, and so can the habits of your followers. A brand whose customers are night-shift nurses will see activity at hours a nine-to-five audience never touches. A national account may have followers spread across several time zones, which blurs any single peak. Content type matters too: a quick text post, a long video and a carousel are consumed differently, and the HubSpot article itself notes that your videos and your images may each have their own best moments.

Because platform matters most, we publish a dedicated guide for each of the major networks. See our guides to the best time to post on Instagram, TikTok, YouTube, LinkedIn and Pinterest. Read the one for the network you rely on most, then come back here for the testing method that works on all of them.

The most reliable evidence is the data your accounts already generate. Most major platforms include analytics that show when your followers are online or how past posts performed, usually in a section labeled insights, audience or analytics. YouTube Studio, for example, has an Audience tab with a chart of when your viewers are on YouTube, and similar activity views exist on other networks once an account has enough followers and enough history to chart. Menus change over time, so look for the audience or insights area of each platform and find the report that shows activity by day and hour.

Start by noting the two or three strongest day-and-hour blocks and the time zone the chart uses, since a mismatch there is a common source of confusion. Then list your last ten or fifteen posts with the day and hour you published them and how each performed in its first day or two. You are looking for a rough pattern, not precision. Compare like with like: a video against a video, a text post against a text post, because format changes results as much as the clock does. If your account is new and the charts are empty, fall back on the published windows from the HubSpot roundup as your working hypothesis.

Next, choose a slot slightly before the peak. Posting an hour or two ahead gives the post time to settle in and be shown as your audience arrives, rather than appearing as they leave. Commit to that slot for several posts, change only one thing at a time, and write down what you see. This is where a scheduler earns its place: it lets you pick the exact slot and hold it consistently without being at your desk at 7 a.m., which is the single biggest obstacle to running a clean timing test.

Here is a sample week for an account that posts on a few channels while running a timing test. The days are examples; swap them for the slots your own analytics point to. The pattern matters most: check data early, schedule ahead of the peak, hold your slots steady, and review at the end of the week.

Week 1: Gather your starting evidence

Spend the first week learning before you change anything. Open the analytics or insights area on every platform you use and screenshot the chart that shows when your followers are active, along with the time zone it uses. Look at your geography or location report too, because followers in a different time zone from yours are a common reason a slot underperforms. List your last ten posts with the day and hour you published them and how each did in its first day or two. If your accounts are new or the charts are sparse, choose a published window from the HubSpot roundup as your working hypothesis for each channel. By the end of the week you should have a written list of candidate slots, one or two per platform, and a note of which networks you will prioritize first.

Week 2: Run your first test slots

Now put your candidates to work. For each priority channel, choose one primary slot a little ahead of your strongest block and schedule your posts into it for the whole week. Keep the content type steady where you can, so you are comparing the clock and not the format. Use a scheduler to queue the posts in advance, which keeps the timing exact even when your day is busy. After each post publishes, spend a short time replying to comments, then record the first-day reactions, saves or shares in a simple sheet next to the time and day. Resist the urge to change slots after one weak result, because a single post is noise. The aim this week is a clean set of comparable data points from a consistent routine.

Week 3: Change one variable

In the third week, introduce a single change and leave everything else alone. If your first slot was weekday mornings, try weekday afternoons, or move the same morning slot to a different day. Changing one thing at a time is what lets you say that the difference came from the timing and not from a new topic or format. Schedule the same type of post in the new slot across the week and track the same metrics you recorded before. Pay attention to platform differences, because a change that helps on one network may do nothing on another. If you manage several channels, run the experiment on the one where you post most often, since it will produce data faster. Write down what you expected before you look at the results, so you learn from any surprise.

Week 4: Compare, decide and lock it in

Use the final week to read the pattern and make decisions. Line up your logged posts by slot and compare like with like, looking for a consistent edge rather than one standout hit. Where one slot clearly held up across several posts, make it your standing time for that platform and schedule your next month into it. Where the results were unclear, keep your current slot and try a different variable next month. Add a recurring fifteen-minute review to your calendar so you check your audience report regularly, because audiences drift over time and yesterday’s best slot is not guaranteed to stay best. Finally, link your timing to your wider routine: with the slots locked and posts queued ahead, you can spend your saved time on replies and conversation, which no timing trick can replace.
