Overlap posting windows
Connect accounts when you want overlap windows calculated from your actual audience geography, post history and approval workflow.
What does the timezone posting planner optimize for?
It finds posting hours in your timezone that land near strong engagement hours for multiple audience timezones on the selected platform.
How many audience timezones can I compare?
You can compare up to three audience timezones at once, which is enough for common mixes such as US East, UK and Australia.
Are the overlap windows guaranteed to be best for my account?
No. The free planner uses aggregate platform curves. TimeToPost account recommendations can use your own audience and post history for a more precise schedule.
Why does one platform prefer different overlap times than another?
Each platform has a different daily engagement shape. LinkedIn tends to cluster around work hours, while TikTok, YouTube and Pinterest often have stronger evening windows.
