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

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.
