The Best Time to Post on Twitter/X in 2025: Based on Data from 1 Million Posts

We analyzed more than 1 million tweets to pinpoint the best time, day, and post format for maximum engagement on X (formerly Twitter).

Timing can make or break many things: Heating leftover pizza in the microwave, delivering a punchline for a joke, canceling a free trial — and it’s no less important when it comes to the best time to post on Twitter.

OK, OK: Posting your tweets at the right time might not be as critical as, say, preventing soggy pizza, but it’s still an important consideration when it comes to your social media marketing strategy.

I hear what you’re thinking: X no longer has a chronological feed — how can the time you post matter so much when X’s algorithm is in the driver’s seat?

Posting times might not be as vital as they were in Twitter’s early days, but they still seem to affect content performance on X.

Remember: X/Twitter’s algorithm values engagement — which is why we used engagement rate as the metric to measure the success of more than 1 million tweets sent through Buffer.

Our findings were fascinating. We uncovered definite patterns in what posting times, days, and content types tend to get more engagement than others, helping us make some recommendations about not only the best time to post on Twitter, but the best day and the best content format to post as well.

Let’s take a closer look.

The best time to post on Twitter/X

The best time to post on Twitter or X is 9 a.m. on Wednesday. Tweets posted at those times tend to have the highest engagement rates, according to our analysis of more than 1 million tweets.

The next best time to post on Twitter is Tuesday at 8 a.m., followed by Monday at 8 a.m.

🌅 Tweeting during mid-morning every weekday tends to yield solid engagement. Other notable posting times are all during this morning period.

The darkest slots represent the time slots with the highest engagement rates and, we extrapolate, the best time to post on Facebook. The light to white blocks are the time slots with the lowest engagement — times that are perhaps left out of your posting schedule.

According to demographic data from Statista, 36.6% of Twitter users are between 25 and 34. The second-largest age group of users, 34.2%, are between 18 and 24. This suggests that Twitter users are likely logging on to check their feeds as they arrive and settle in at work in the morning.

On most weekdays, the peak hours for social media engagement are similar. Engagement tends to climb from the early morning on weekdays, peaking at around 9 a.m., then slowly petering out in the early afternoon, towards the end of the workday.

Wait, what time zone? To make this data easier to understand, our data scientist Bufferoo has done some mathematical magic to make the recommended time zones universally applicable. In other words, no need to convert — consider all the recommendations local time. Whether you're in EST (Eastern Standard Time), PST (Pacific Standard Time), or IST (Indian Standard Time), the times apply to you.
