The studies behind the times
Each social media company studied its own customers' posts, so the answers differ. Every study here gives its times in local time, adjusted to where the followers are. Our guides explain what each one measured.
| Network | Study | Time zone, as the study says it |
|---|---|---|
| Sprout Social March 2026 | Local time | |
| Buffer September 2026 | Normalized to your local time | |
| Hootsuite July 2026 | Localized across 118 countries | |
| TikTok | Sprout Social March 2026 | Local time |
| TikTok | Buffer September 2026 | Adjusted so you don't need to convert; no zone named |
| Sprout Social March 2026 | Local time | |
| Buffer September 2026 | Normalized to the local time zone you target | |
| Hootsuite November 2025 | Localized across 118 countries |
Buffer's TikTok page names no time zone. It says its times apply anywhere, with no need to convert, so they're read as local time like the rest.
How to use the times
- Start with a day the studies agree on, then check when your own followers are online.
- Instagram Insights and TikTok Studio show your followers' most active times; LinkedIn shows where your followers are, so you know whose clock to use.
- Test two or three time slots for two to four weeks, compare posts at the same age, and keep the slot that works.
- In Unisenda, you pick the day and time to the minute, and the calendar's week view lays your test slots out hour by hour.
Questions people ask
Which time zone are these times in?
Your audience's local time. Each study gives the hour where the followers are, so 9 a.m. means 9 a.m. for them. Pick the city where most of your followers live, and the tool shows the same moment on your own clock.
Why do the studies disagree?
Each company studies its own customers' accounts, measures engagement its own way and covers different months. Treat any time as a first guess to test, not a rule.
What happens when the clocks change?
The tool works out each time for its actual day in the coming week, so a week when one country has changed its clocks and the other hasn't yet still comes out right.
How do I find my own best time?
Instagram Insights and TikTok Studio show when your followers are most active, and LinkedIn's analytics show where they are. Test two or three time slots for a few weeks and keep what works for your audience.
Can Unisenda post at these times for me?
You choose the day and time for each post, and Unisenda publishes it then, even with your phone and computer off. It doesn't pick a time for you.
