January 25: the feast the Church chose for a conversion nobody dated

Original prompt & settings (JSON) ↗The calendar is more certain than the event. 25 January is a date the Roman Catholic Church selected; the encounter it commemorates cannot be pinned to a year, let alone a day.
What 25 January 42 actually marks
No surviving ancient text dates Paul's conversion to 25 January, and none dates it to the year 42. The date is the Roman Catholic Church's annual commemoration, the feast of the Conversion of Saint Paul, and a liturgical calendar entry is not evidence of an anniversary.
The feast's 25 January date is traditional rather than historical. Its Catholic lectionary offers the conversion narrative from either Acts 22 or Acts 9.
The years the historians actually offer
Where the calendar is precise, the chronology is not. A Cambridge scholarly chronology illustratively places the conversion around 32/33 CE, and other reconstructions differ from it by several years.
The problem is in the sources. Paul's own account in Galatians describes a revelation and a commission to preach among Gentiles without supplying a date, and Acts narrates the episode without anchoring it to a year.
The episode under the feast day
In Acts, Saul is travelling under priestly authorization to arrest followers of Jesus when a light and a voice stop him on the road to Damascus. His companions lead the would-be arresting officer into the city by the hand.
He is blind for three days until Ananias visits him, then is baptized and begins proclaiming Jesus. Acts tells the story three times and the versions differ over what the companions saw and heard.
Two familiar details are absent from every biblical version: there is no horse, and Saul is not renamed Paul at the encounter — Acts 13:9 simply calls him "Saul, also known as Paul."

What the sources leave uncertain
- The ISO date preserves the listed traditional date, but neither its year nor its month and day is a verified date for the historical encounter.
- A Cambridge scholarly chronology places the conversion around 32/33 CE; other reconstructions differ by several years.
- January 25 is solidly verified as the modern Roman Catholic feast, but not as the historical anniversary.
- Paul’s own letters and Acts differ in emphasis: Paul describes revelation and calling, while Acts supplies the dramatic narrative details.
