How this best time checker works
The checker loads the most recent posts of the account you enter, from 40 up to 100. It keeps original posts and drops replies and reposts, because a repost shows someone else's numbers. For each post it calculates engagement rate, then averages those rates for every weekday and hour in your local time.
- Top slots are the three weekday-and-hour combinations with the highest average engagement rate. Slots with a single post are used only when the sample has no slot with two or more.
- The heatmap shows all 168 weekday-and-hour slots. Darker cells earned higher average engagement. Empty cells had no posts, so they tell you nothing.
- Weekday averages show which days lead overall, which is more stable than a single hour.
Treat the result as a hypothesis. Post in the top slot for two to three weeks, then check again. Your own results matter more than a general chart. For more on the numbers behind a post, try the X profile analyzer, which also shows engagement rate, views and breakout posts.
Best time to post on X: FAQ
What is the best time to post on Twitter (X)?
It depends on the account. Large studies of many accounts often point to weekday mornings or early afternoons, but the best time for your own audience is the slot that earns the highest engagement rate in your own recent posts. Enter your handle above to see it.
Is this tool free?
Yes. It is free, needs no signup or login, and has no paywall.
Do I need to connect my X account?
No. It reads the public posts of the handle you enter. It never asks for your password or access to your account.
How is the best time calculated?
The tool takes the account's recent original posts, skipping replies and reposts. For each post it calculates engagement rate, which is likes, reposts, replies, quotes and bookmarks divided by views. It averages those rates for each weekday and hour, in your local time, and ranks the slots.
Why does the tool say a slot has too few posts?
One post is not enough to tell a good slot from luck. The tool ranks slots with at least two posts when it can, so load a bigger sample of 60 to 100 posts to get more reliable slots.
Why do times change between accounts and days?
Audience location, time zone, topic and posting habits all change when people are online. A slot that works for one account can fail for another, so measure your own account rather than copying a generic chart.
How often should I check the best time?
Check once every few weeks. Posting habits and audiences shift, so a best time from three months ago may no longer hold.
