Best Time to Post on Instagram on Thursday (2026 Data)
The short answer: Thursday morning, 8–9 a.m. audience-local — the single best slot of the entire week in Buffer's 9.6M-post dataset, and the only day its data goes morning-first. Sprout's window is 12–2 p.m.; Later says 4–5 a.m.
What the three big studies say about Thursdays
| Study | Dataset | Best Thursday time |
|---|---|---|
| Buffer | 9.6M posts | 9 a.m. — its #1 slot of the week (then 8 a.m., 7 a.m.) |
| Sprout Social | ~2B engagements | 12–2 p.m. |
| Later | 6M posts | 4–5 a.m. |
Thursday is the anomaly: every other day, Buffer's peaks are evening; Thursday flips to morning, emphatically — three consecutive morning hours top its chart. Combined with Sprout's lunch window, Thursday's whole value is packed into 7 a.m.–2 p.m. The full guide explains the methodology differences behind splits like this.
Is Thursday a good day to post on Instagram?
Top three. It trails only Tuesday/Wednesday in Sprout's ranking and owns Buffer's #1 individual slot. For B2B and professional audiences it's arguably the best day: engagement is concentrated in work-adjacent hours.

Thursday FAQ
Thursday or Friday? Thursday, in both major datasets — Friday is Buffer's late-night outlier and Sprout's flattest weekday. Is 9 a.m. really the best time of the whole week? In Buffer's median-engagement methodology, yes. Sprout's volume methodology disagrees. Treat it as the strongest morning bet on the calendar, then verify in Insights. Thursday morning or afternoon? Morning per Buffer, early afternoon per Sprout — the safe read: anywhere 8 a.m.–2 p.m. beats Thursday evening.
