The best times to post on Twitter and LinkedIn in 2026

Timing is the lowest-effort lever you have: the same post, in front of more people, just for choosing a better slot. On Twitter, midweek mornings win. Tuesday 9 AM is the single most defensible slot, and Tuesday through Thursday between 9 and 11 AM is the reliable window, with Wednesday the strongest day overall. Evenings and weekends underperform for reach. On LinkedIn, the peak shifted later in 2026: Wednesday 4 PM is the standout, with Wednesday-to-Friday afternoons strong and the classic Tuesday-to-Thursday late morning still working. Mondays and weekends are quiet.

Why this is a grid, not an hour-by-hour heatmap

A lot of “best time” tools show a slick 7-by-24 heatmap with a single glowing pixel at, say, 9:47 AM. That precision is invented. The underlying research, Buffer’s 2026 analysis of 8.7 million tweets and 4.8 million LinkedIn posts, reports coarse windows stated in the audience’s local zone, not exact minutes. So we render exactly what the data supports: a day by part-of-day grid. A fake hourly heatmap would look more authoritative and be less true, and we would rather be useful than impressive.

How to use it without overthinking it

• Put your best post in your best window. If you only nail one slot a week, make it the “Best” cell, and give it your strongest content, not a filler post.

• Use afternoons and evenings for conversation. Replies and casual takes, not your reach-builders.

• Then trust your own data. These windows are a strong default, but your audience’s real behavior beats any average once you can see it.

Timing is a small lever compared to what and how often you post. The full system, frequency, content mix, and a sample weekly calendar, is in our personal brand posting schedule for Twitter and LinkedIn. And once you are posting, the engagement rate calculator tells you whether a slot is actually working.
