Best time to post calculator, from your own history

Paste your own past posts — a weekday, a time and an engagement number per line — and this calculator averages your real engagement by time slot and highlights your best-performing one. It is genuinely different from the best-time-to-post cheat sheet, which is a general, published 2026 benchmark, the same for every visitor. This one only uses the numbers you type in.

One post per line: weekday, time (24h or am/pm), engagement number. Nothing is uploaded — this runs entirely in your browser.

Your best slot

Paste at least one post to see your averaged best slot.

How to use the personalised best-time calculator

  1. Gather your last 10-20 posts. Pull the posting day, posting time and total engagement (likes plus comments plus shares) for a handful of recent posts.
  2. Enter one post per line. Type each post as a weekday, a time and an engagement number, for example "Wed, 14:00, 212".
  3. Review the averaged slots. The calculator groups your posts by weekday and hour and averages the engagement in each slot you used more than once.
  4. Read your top slot. The highest-averaging slot is shown first, along with how many of your posts it is based on.
  5. Post there again and re-check. Try posting in that slot for a few more weeks, then paste your updated numbers back in to confirm the pattern holds.

Worked examples

Three posts at the same slot average out

Three separate Wednesday 2pm posts with 180, 212 and 240 engagement average to 210.7 for that slot — a real average, not a single data point.

A one-post slot is shown with its sample size

A slot backed by only one post still appears, but the tool always shows the post count next to it so a single high number does not read as a trend.

Personalised best-time calculator FAQ

How is this different from the best-time-to-post cheat sheet?
That page is a static, general benchmark, identical for every visitor. This calculator only uses your own pasted post history.
What counts as "engagement" in the number I enter?
Whatever total you want to optimise for — commonly likes plus comments plus shares for one post, in whatever units your analytics report.
How many past posts do I need for a useful result?
More is better — a handful of posts per slot gives a real average, while a single post per slot is just one data point.
What format does the time need to be in?
A 24-hour time like 14:00, or a 12-hour time like 2pm — both formats are read correctly.
Does the calculator use any data beyond what I paste in?
No — there is no connected account and no external benchmark involved; every number comes only from what you typed.
Does this tool store or send my post history anywhere?
No. The averaging happens entirely in your browser as you type — nothing is uploaded or saved.
Does SkedCast offer an automatic version of this for connected accounts?
Yes — SkedCast’s built-in best-times feature learns the real optimal time for every connected account automatically, without any pasting.
