How to use this tool
Choose your platform — Instagram, TikTok, Facebook, LinkedIn, X or YouTube — from the first dropdown. Pick a specific day if you're planning one post, or leave it on "Any day" to see the strongest windows across the whole week. Select Consumer for a general audience, or B2B if you're posting for professionals and decision-makers. The tool instantly updates the answer line, your best 2–3 posting windows in UK time, and a colour-coded weekly heat grid showing engagement strength for every day and time block.
Common posting-time questions
What are the 5-3-2 and 5-3-1 content rules?
Both are content-mix guidelines, not posting-time rules. The 5-3-2 rule suggests that out of every 10 posts, 5 should be curated from other relevant sources, 3 should be your own original content, and 2 should be personal or fun posts that show personality. The 5-3-1 variant is nearly identical, just with a slightly different personal/promotional split. Either way, the goal is a balanced feed rather than constant self-promotion.
What is the 5-5-5 rule for social media?
It's a daily engagement habit rather than a posting-time rule: spend around 5 minutes engaging with 5 posts in your niche, using or checking 5 relevant hashtags, each day. Pairing that habit with one of the posting windows above covers both sides of the algorithm — what you post and how you show up between posts.
What is the golden hour to post on Instagram?
The "golden hour" is the first 30–60 minutes after you publish, the window Instagram's algorithm watches most closely to decide how far to distribute a post. Posting inside one of the windows above, then staying active to reply to early comments and DMs, is what most creators mean by making the most of the golden hour.
Good timing gets a post seen — a bigger audience gets it seen by more people. Grow your Instagram audience or boost your TikTok followers to make every well-timed post count for more.
