Do you have any references or evidences? Seems they do not mention anything about the scheduled time in https://forge.rust-lang.org/release/process.html#release-day-thursday.
Also it seems to be always on Thursday.

This is based on observations and looking at rust release calendar: https://calendar.google.com/calendar/ical/mozilla.com_ts4qudb88i0tbjef8rche4a6v4@group.calendar.google.com/public/basic.ics, and because stable release is done every 6 weeks, this means it happens every Thursday.

That link shows an event on UTC 1700-1800, is it the time they click the release button or only started the CI jobs?
I checked the last-modified time of the channel TOML, which seems to be fairly random:

Builds happen way prior that's just target time that all work is pushed through AFAIK.

dot releases are more chaotic as they are done on as needed basis (so they are outlines).

The point zero releases are not as stable as you mentioned either.

But they are all before 17:00. Sometimes there are also last minute fixes to rc version.
run only on Thursday

This is best-effort anyway, it doesn't cost anything, we just try to do our best to get stable versions sooner. |

Instead of bikeshed over the exact timing maybe we could just run this multiple times per day? It's a bummer to wait 24h no matter when the new rust release ships. And, action runs are cheap overall especially for open projects. |

Thank you @oxalica!! |

Thank you! We are in JST timezone so we usually end up seeing a release in morning and then having to wait few hours to use it... |
