Contextual Lab · calendar model, not a second dossier
Passover & Crucifixion Calendar Lab
Change the surviving 30 CE / 33 CE reconstruction and inspect how civil dates, Passion events, and the Friday–Saturday–Sunday sequence move together. The historical argument is canonical in the Dating the Crucifixion Research Thread.
Canonical split: use the Research Thread for the evidence argument; use this lab to manipulate the date model and Passion sequence.

Model comparison
Two surviving Friday reconstructions
The lab uses proleptic Gregorian civil dates while preserving the same astronomical instants used in older Julian-calendar literature.
Favored reconstruction
Friday, 1 April 33 CE
Jewish date
Nisan 14 in the standard reconstruction
Julian equivalent
Friday, 3 April 33 CE
Burial
Before sunset Friday, 1 April
Sabbath
Saturday, 2 April
First day
Sunday, 3 April
Fits the longer Johannine public-ministry reconstruction more naturally. The same civil day also carries a real partial lunar eclipse later in the evening.
Principal alternative
Friday, 5 April 30 CE
Jewish date
Nisan 14 in the standard reconstruction
Julian equivalent
Friday, 7 April 30 CE
Burial
Before sunset Friday, 5 April
Sabbath
Saturday, 6 April
First day
Sunday, 7 April
Remains calendrically viable under a compressed public-ministry reconstruction.

33 CE astronomy audit
What the eclipse does—and does not—add
The astronomical event is certain; its historical and theological interpretation is not.
Calculated event
Partial lunar eclipse · 1 April 33 CE Gregorian
The same event is catalogued as 3 April 33 CE in the Julian calendar used by NASA and much of the crucifixion literature. NASA gives an umbral magnitude of 0.5764. This makes the eclipse a genuine coincidence with the 33 CE calendar candidate, not the reason that candidate exists.
Humphreys and Waddington connect the eclipse with Peter's quotation of Joel, but Acts 2 is itself scriptural quotation rather than a direct report that observers saw an eclipsed Moon. Bradley Schaefer's glare analysis further argues that this partial eclipse would not have appeared blood-red because of the eclipse itself.
The midday darkness was not a normal solar eclipse
Passover falls near full Moon. Solar eclipses require new Moon. Therefore the Synoptic darkness from roughly noon to 3 p.m. cannot be explained by an ordinary solar eclipse if the Passover chronology is retained.
