Why a generic answer does not hold up
Any published "best time" figure is an average across accounts with completely different audiences: different time zones, different habits, different reasons for being on the platform. Applying that average to a specific account is a guess, not a fact about that account's real followers.
Why timing matters more on X than on some other platforms
Since early reply and engagement velocity carry real weight in how far a post travels, publishing when a meaningful share of your audience is active gives a post a head start over the same post published into a dead window. That is before content quality enters into it at all.
How to find your own window
Check your own account's analytics for when your specific followers are active, then post consistently around that window for a few weeks and compare early engagement, not just final totals. Your own account's history is a far more reliable guide than any generic benchmark.
