Best Time to Post Analyzer (From Your Own Data)

About the Best Time to Post Analyzer (From Your Own Data)

Generic “best time to post” charts average other people’s audiences. This analyzer uses yours: open an export of your posts — CSV or Excel, from your platform’s analytics or a sheet you keep — and it finds when your own posts did best. Every post gets a score (likes, comments, shares and saves added up, or views, or any columns you choose, optionally per 1,000 people reached), and each day of the week and hour is compared with your average post.

You get a grid of days and hours, the best slots with how many posts each rests on, the best days and hours, your top posts, and how each post type and hashtag does. Times are read in the time zone of the file and shown in the one you choose, such as your audience’s, with summer time handled. Everything runs in your browser.

Without a pass, the free preview shows the counts of your posts in full, with the first half of the best slots, of the grid’s rows and of each table; the full analysis, Copy summary, the CSV and printing come with a Pro pass.

Common uses

• Choosing when to schedule next month’s posts from what worked for your own followers.
• Showing a client which days and hours their content does best, with the number of posts behind each.
• Comparing Reels, carousels and photos, or videos and Shorts, by how they score.
• Seeing which hashtags come with your best-performing posts.

How the score and the slots work

• Each post’s score is the sum of the columns you choose. With a reach, impressions or views column, the score is that sum per 1,000 of it, so a post shown to more people does not win just by being shown more.
• Each slot (a day of the week and an hour, in the time zone shown) gets the average score of its posts, or the median, which a single viral post moves less.
• The figure beside each slot compares it with your average post: +25% means its posts scored a quarter more than your typical post.
• The best slots are those with at least the number of posts you set (2 by default), so one lucky post does not top the list. The grid can show blocks of three hours when your posts are spread thin.

Time zones

Analytics exports write times in a time zone: the account’s, the device’s, or UTC. Choose it under The file’s times are in; when a file writes each time with its own offset (“+05:30”, “Z”), that offset is used instead. Then choose the zone to show days and hours in: your audience’s, if most of them live in one place. The conversion uses your browser’s time-zone data, so summer time is right on both sides, including the days the clocks change.

Exports it reads

• CSV, TSV and Excel files (.xlsx, .xls, .ods), and rows pasted from a spreadsheet. An export with a title or notes above its header row is read from the header row.
• Dates and times as exports write them: “2026-10-15 14:30”, “10/15/2026 2:30 PM”, “15.10.2026 14:30”, “Oct 15, 2026”, a Unix time, or an Excel date. When every date could be read day first or month first, choose the order.
• Rows without a time or without results (a totals row, an empty line) are left out and counted.
• YouTube Studio’s export of the current view has at most 500 rows (YouTube Help).

Limitations

• The figures show what happened with your posts, not why: a good slot can be a coincidence of what you posted then. Try the best slots for a few weeks, then compare again.
• Older posts have had longer to collect results; an export that ends a few days before today compares posts more fairly.
• If the export gives only the publish date, without a time of day, only the days of the week are compared.
• Column names are recognised in English; for an export in another language, choose the columns yourself.
• Up to 50,000 posts and files up to 30 MB.
