Best Times to Post on X (Twitter) in 2025

Introduction

In the fast-paced world of social media, timing is everything, especially on platforms like Twitter (now X). With 500 million tweets sent out daily—equivalent to 6,000 tweets per second—it can feel overwhelming to stand out. But here's the good news: knowing when to post can make a significant difference in your engagement.

At Assembly, we’ve done the heavy lifting for you by analyzing data from thousands of Twitter accounts to determine the optimal times to tweet (now updated for 2025). Whether you’re a brand looking to boost visibility or a content creator aiming to connect with your audience, posting at the right time is key.

Why Post Times Matter

Twitter’s algorithm prioritizes recent content, meaning that your tweets have a better chance of being seen if they’re posted when your audience is active. With Twitter's switch back to a chronological feed option, timing is more crucial than ever.
