The short answer

Post on weekday mornings, 9 AM to noon local time.

Six engagement studies published between November 2025 and August 2026 disagree on the hour: Buffer's top hour is 9 AM, Sprout Social's band runs 12 to 6 PM, and Social Champ's best is Sunday 9 AM. The widest agreement is weekday mornings, roughly 9 AM to noon in your audience's local time, with Tuesday to Thursday the best days. Late evening and Saturday score lowest.

X itself gives no clock time. Its open-source ranking code drops posts older than 48 hours from the For You feed, so a post has about two days to find its audience. Use the map above as a start, then test it against your own numbers.

What changed

What changed for timing. X opened its ranking code.

  1. Aug 2026

    X published its ranking weights

    X added the weights its feed uses to blend predicted actions, such as likes and replies, into one score, and a note on how those weights work. Source

  2. Jan 2026

    The For You algorithm went open source

    X open-sourced its new For You ranking, built on the same transformer design as xAI's Grok. The code removes posts older than 48 hours, so recency still counts. Source

Tips

Find your own best time. The map is a start, your numbers decide.

  1. Plan in your audience's time zone

    Most studies use the audience's local time. If most followers live in New York, plan in Eastern Time, wherever you are.

  2. Schedule the morning posts

    The best band starts around 9 AM. Schedule posts ahead so they go out on time, even before your workday starts.

  3. Skip the late evening

    Buffer calls 6 to 11 PM the worst time, and OpenTweet finds weekday late nights after 10 PM the lowest. Save evenings for replies.

  4. Test one slot at a time

    Post the same kind of content at two times for two to three weeks. Compare impressions and replies per post, not likes alone.

  5. Judge a post within two days

    X's code drops posts older than 48 hours from For You. Compare slots on their first two days of numbers.

  6. Do not chase the minute

    The studies disagree on the hour, from Buffer's 9 AM to Sprout Social's 12 to 6 PM. A strong post at a fair time beats a weak post at the best time.

How we built this guide. Checked on October 17, 2026.

We read the 2025 and 2026 X timing studies from Sprout Social, Buffer, Hootsuite, SocialPilot, Social Champ and OpenTweet. Together they cover about 14 million posts plus Sprout Social's 2 billion engagements. Each study gets one vote per day and three-hour block: plus one when it names the block as a best time, minus one when it says to avoid the block or the day. The votes are scaled from 0 to 100, so the map shows where the studies agree, not an engagement rate. Left out: RecurPost (no sample or method), Metricool (no day-by-day data in 2026), Emplifi (one coarse row for X) and HubSpot's survey of marketers, which measures opinion.

  1. Sprout Social: Best times to post on X in 2026Mar 31, 2026Nearly 2 billion engagements across about 307,000 profiles on all networks, Nov 2025 to Feb 2026.
