Darker cells = higher engagement. Hours shown in your local timezone. Hover (or tap on mobile) for the score.
Drop your post into SocialCal's calendar and publish across every platform at each one's optimal hour.
Better posting time isn't one number — it's how the algorithm, your audience, and your cadence interact. Here's how to use it.
Pick the platform you're posting to. The calculator pulls a schedule calibrated against the 2026 Sprout Social, Hootsuite, Later, and Buffer reports, then converts it to your local timezone using your browser's Intl API.
The top-3 windows shown are the highest-engagement two-hour blocks across the week — drop your most important post of the cycle into one of them.
Most platforms test fresh posts on a small early audience before deciding whether to expand distribution. Instagram evaluates the first 30–60 minutes for engagement velocity. TikTok's For You grades the first 90 minutes against completion rate, replays, and shares. LinkedIn tests every post on close connections, then expands proportional to comment quality.
Posting when your audience is asleep means failing that early-engagement test and getting buried.
Across every platform we tested, posting the same time every day outperforms chasing the "perfect" slot inconsistently. LinkedIn, TikTok, and YouTube reward predictable cadence because regular posting trains the recommendation system to surface your content to your audience pre-emptively.
Pick one or two windows and stick with them for a full quarter before re-evaluating.
Each platform's schedule is built from the public 2026 reports of Sprout Social, Hootsuite, Later, and Buffer, cross-referenced against engagement-velocity patterns each platform's own creator documentation describes. We update quarterly.
Treat the calculator as a strong default, then layer your own analytics on top after 30 days of consistent posting.
Each calculator is calibrated separately — algorithms differ in how they reward early engagement, watch-time, and posting cadence.
