Best time to post in the UK, across eight platforms

Both matter, in that order. Timing sets the ceiling and content decides where under it you land. Every major platform weights the opening period of a post heavily, so content published when your audience is asleep starts from a standing position it usually cannot recover from. Good content at a poor hour still beats poor content at a good one.

For most UK accounts the strongest Instagram windows sit on Tuesday, Wednesday and Thursday evenings between seven and nine, with a secondary lunchtime peak around midday. That is the general shape. The tool above narrows it by format, industry, audience and objective, and those four answers routinely move the peak by two hours or more.

TikTok runs later than Instagram and holds up far better at weekends. Evening windows from seven to ten hold across the week, and Friday and Saturday nights stay strong where Instagram falls away. TikTok also keeps distributing content for days rather than hours, so a missed peak costs less there than anywhere else.

Not if you schedule in your device's local time, because your clock already moves. If your scheduling tool asks for a fixed zone, choose Europe slash London rather than GMT, so it follows the change automatically. The clock selector in the tool lets you see either version.

Because format changes the answer more than industry does. Short video is consumed in the evening and on the sofa. Carousels and articles are read at a desk in the morning. A tool that gives a LinkedIn newsletter and a LinkedIn Reel the same posting slot is averaging two different behaviours into one wrong number.

Three to five times a week suits most brands on Instagram, and TikTok tolerates more. Set the frequency in the tool and the schedule returns exactly that many slots rather than a full week you will not keep to. Consistency beats volume: three posts a week every week outperforms seven posts one week and nothing the next.

No. The window is wider than the number suggests, and seven and half past seven behave almost identically. Publishing fifteen to thirty minutes ahead of the peak is often slightly better, because it gives the platform time to test the post on a small group before the main wave arrives.

Choose the East or West coast option rather than a single United States setting, because the two are five and eight hours behind and a window that suits one misses the other. The tool then shifts you towards genuine overlap hours, at the cost of some UK evening reach.

The curves are a model rather than a measurement. They combine published 2026 platform and industry benchmarks with the posting patterns we observe running client accounts. Scores are an index against your own peak hour, not a predicted engagement rate, and the methodology section states the limits plainly.

No. The entire calculation runs in your browser. There is no sign up, no email field, and your selections are never transmitted anywhere. The calendar file is generated on your device too.

People are on their phones at weekends, but they engage with brand content less. The effect is strongest on LinkedIn, where Saturday and Sunday are close to dead, and weakest on YouTube and Pinterest, which both improve at weekends. Travel, hotels and gaming also hold up, which is why the industry answer changes the weekend shape.

Yes, and freelancers and agencies do. Run it per client, copy the schedule or download the calendar file, and keep the settings you used so the next review starts from the same baseline. There is no limit and no attribution required.
