Short answer: Post during the waking hours of the instances your followers are on. Mastodon timelines are chronological, and every instance has its own home crowd and timezone. Check where your followers live, find the overlap, and schedule there. Boosts carry your post across federation, so aim for the hour your most active boosters are online.
Why Mastodon timing is different
- Chronological timelines. Home, Local and Federated timelines show posts in order. No ranking pulls an old post back up. Mastodon documents the timelines in its network guide.
- Your instance has a timezone. A German instance wakes up at a different hour from a US one. Your followers are spread across instances; their home servers tell you where they are.
- Federation spreads via boosts. Your post reaches other servers through followers and boosts. One boost from an active account in the right timezone is worth more than a perfect clock time.
- Local timeline is a bonus audience. On a niche instance, posting when the Local timeline is busy puts you in front of members who don't follow you yet.
How to find your best time on Mastodon
- Map your followers' instances. Open your followers list and tally the top servers. Note each server's region and language.
- Read the Local timeline. Check your own instance's Local timeline at a few times of day. Busy hours there are your local window.
- Watch your boosters. Note who boosts you most and when they post. Their active hours are your federation window.
- Test two hours. Alternate for two weeks; compare boosts and replies in the first 2 hours. See A/B testing posting times.
Timezones
Set the timezone in your Mastodon preferences so your own view lines up (preferences docs), then schedule for your followers' main zone. Spread across Europe and North America? European evening is US morning — use the timezone posting planner.
Schedule Mastodon posts in that window
TimeToPost schedules Mastodon posts to your own instance account and publishes at the hour you set. Mastodon supports scheduled statuses natively in its API (scheduled_at); TimeToPost puts that next to your other networks in one queue. Walkthrough: schedule Mastodon posts.

FAQ
Does Mastodon have an algorithm?
No ranked home feed. Timelines are chronological, so timing and boosts drive reach.
Does my instance change my best time?
Yes. Your instance's crowd and your followers' instances set the hours that matter.
Should I use hashtags?
Yes. Mastodon search and discovery lean on hashtags, and people follow them. Add 1–3 relevant ones.
Are boosts or time more important?
Both. Post when your top boosters are online.
