A Protestant Looks At Holy Week

[Terraceth]

No OFFICIAL readjustments are possible without the Sanhedrin. Hillel II recognised that the Sanhedrin's days were numbered and introduced a calendar which allowed for a (more or less) accurate setting for the beginning of the year - thus the system currently in place has been set by the Sanhedrin.

Are you sure? I thought the current adjustments were set by Maimonides in the 12th century.

A polite challenge ... Such a refreshing change

This site addresses some details about the introduction of the current Jewish calendar.
Encyclopaedia Britannica (heavy reading) gives the development of the process for devising the current calendar as around 200, with Hillel II publishing the method in 358/9.
Some sources attribute fine tuning to succeeding centuries through to the tenth, but I haven't seen anything mentioning developments continuing into the 12th.

Well, I tried doing some extra research, then eventually just sort of thought "well, it's not that important" and opted to quit. But from what I read, it seems that Maimonides may not have adjusted the calculations so much as being the one who wrote them all down in the Mishneh Torah and thereby finalized them. But in regards to Hillell II, that story may very well be a myth, with there being no reference to it in the Talmud and the first reference to him doing so coming about 600 years after the fact; it seems that whenever the calculations were finalized, it was at some point after Hillel II.

Valuable information in that Ajdler reference. Rosh Hashanah on a Sunday in 505 AD ... By no means the only important information, but it does remove any doubt that back-to-back Sabbaths (deutero Sabbath + weekly Sabbath) were not only possible, but that they continued until much later than my previous information indicated.
