To be clear, the time probably needs to be expressed via UTC / GMT or other time zone labels.
I regularly post across ~half a dozen communities, the most frequent being to my own, where I post at 9AM (UTC-4 / EST zone) so as to hit early risers in the States and afternoon surfers in Europe. But with other posts, I get the sense that it would be better to post later in the day to hit more viewers. I’m just not sure when that would be.
TBC, I usually use the PieFed scheduler to post, so it’s no problem for me posting at any time of the day.
Thanks for any insight!


It should, but federation is definitely not perfect. Posts usually federate pretty much instantly, but I have absolutely had the occasional post that took an hour or more to federate out to a remote instance for whatever odd reason.
Similarly, I’ve seen delays in people reacting to certain posts in situations where typically there’d be at minimum a couple quick ‘nibbles.’ Had some of that just last week IIRC.
