Best time to post on X (Twitter)
The two large studies of X disagree on the hour but agree on the days. Both day by day, and a planner for your time zone.
Darker = more of the 2 studies name that hour. Times are your audience’s local time.
- Monday 9 a.m. · named by Buffer
- Tuesday 9 a.m. · named by Buffer
- Wednesday 10 a.m. · named by Buffer
The file adds 3 repeating 15-minute events with a 10-minute alert, in your audience’s time zone, to Google Calendar, Apple Calendar or Outlook. It is built in your browser; nothing is uploaded.
The best time to post on X depends on the study: Buffer’s 8.7 million tweets did best from 9 to 11 a.m. every day, with Tuesday at 9 a.m. on top, while Sprout Social sees the most engagement Tuesday to Thursday from 12 to 6 p.m. Both rank midweek highest and Saturday lowest, so start midweek and test one morning and one afternoon slot.

X (Twitter): best times by day, study by study
All times are the audience’s local time. The last column shows hours at least two studies name.
| Day | Sprout Social | Buffer | Shared hours |
|---|---|---|---|
| Monday | 2-3 p.m. and 5 p.m. | 9 a.m., then 10 a.m. and 8 a.m. | no shared hour |
| Tuesday | 12-6 p.m. | 9 a.m., then 10 a.m. and 11 a.m. | no shared hour |
| Wednesday | 12-6 p.m. | 10 a.m., then 9 a.m. and 11 a.m. | no shared hour |
| Thursday | 12-6 p.m. | 9 a.m., then 10 a.m. and 8 a.m. | no shared hour |
| Friday | not in its top windows | 9 a.m., then 10 a.m. and 11 a.m. | no shared hour |
| Saturday | not in its top windows | 9 a.m., then 10 a.m. and 11 a.m. | no shared hour |
| Sunday | not in its top windows | 9 a.m., then 10 a.m. and 8 a.m. | no shared hour |
Morning or afternoon on X
Buffer ranks each posting hour by the engagement rate the tweets earned, and mornings win on every day of the week. Sprout Social counts when engagement happens and finds noon to 6 p.m. busiest, Tuesday to Thursday. The two lists share no hour, which is itself useful: the “best time” depends on what you measure.
Because X moves fast, the day matters as much as the hour. Both studies agree on Tuesday to Thursday and on Saturday being the weakest day.
What each study measured
| Study | Measures | Sample | Period | Days |
|---|---|---|---|---|
| Sprout Social | when engagement happens: hourly windows with the most likes, comments and shares across Sprout customers’ profiles | nearly 2 billion engagements on about 307,000 profiles (30,000+ Sprout customers) | 27 Nov 2025 to 27 Feb 2026 (published 2026-03-31) | Best: Monday to Thursday. Worst: Saturday |
| Buffer | which posting hour earned the highest median engagement rate for posts published through Buffer | 8.7 million tweets | published 2026-03-13 | Best: Wednesday, then Tuesday and Thursday. Worst: Saturday |
Find your own best time on X (Twitter)
- Start with a shared slotUse the hours most studies agree on for your first posts, in your audience’s local time.
- Test one alternativeFor two weeks, post similar content at one shared slot and one slot only a single study names, same days each week.
- Compare like with likeCompare reach or views per post after the same number of hours, not total likes days later.
- Check X analyticsX shows views and engagements for each post but no chart of when your followers are online. Post at different hours for two weeks and compare views and engagements per post.
Limits and when to use something else
- Study times come from their customers’ accounts, mostly brands. Your audience can differ, especially outside the US and Europe.
- A great slot does not rescue a weak post: the first seconds of a video or the first line of a caption matter more than the hour.
- Where the studies disagree, neither is wrong; they measure different things. Test instead of picking one.
Frequently asked questions
What is the best day to post on X (Twitter)?
Wednesday in Buffer’s data, followed by Tuesday and Thursday. Sprout Social found Monday to Thursday strongest.
What is the worst day to post on X?
Saturday, in both Buffer’s and Sprout Social’s data.
Why do the studies disagree about X?
They measure different things. Buffer ranks posting hours by engagement rate; Sprout Social measures when engagement happens across profiles. Test a 9-10 a.m. slot against a 12-2 p.m. slot on the same weekday.
Is the best time to post on X the same in India, the UK or Australia?
Yes, as a local time. Every study here converts times to the audience’s own time zone, so 9 a.m. means 9 a.m. in Mumbai, London or Sydney. What changes is your own clock when your audience lives somewhere else: set both time zones in the planner above to see the slot in your time.
Turn one idea into a week of posts
The hard part of posting at the right time is having something ready. Koldflux Studio turns one recording, idea or script into Shorts and carousel posts you approve and export, so the slots in your calendar are filled. It does not publish or schedule posts for you.
