Sundays on X (Twitter)

Sunday has a distinctive double profile: a relaxed late-morning window, a quieter afternoon, and then one of the best engagement blocks of the entire week on Sunday evening, when audiences scroll while bracing for Monday. The "Sunday scaries" window (7–10 PM local) is prime time for inspirational, planning and entertainment content alike.

X (Twitter) is the most time-sensitive of the major platforms: the half-life of a post is measured in minutes, not hours, and most impressions arrive in the first hour. The For You tab buys you some catch-up distribution, but reply velocity in the first 15 minutes is still the strongest amplifier. That rewards posting into peak commute and work-break windows — mid-to-late morning is consistently the densest period, when professional audiences are between tasks and reply rates are highest.

Knowing the window is half the job; actually hitting it is the other half. TimeToPost schedules your X (Twitter) posts and threads into these exact engagement windows every Sunday, automatically, and then feeds the results back into this dataset so the recommendations keep getting sharper.
