I guess you didn’t see my reply when asked the same question earlier…
From the articles on Jesus and St. Paul in the 1912 Catholic Encyclopedia at , the probable dates of Jesus’ crucifixion and death and St. Paul’s conversion was A.D 29 and A.D. 35, respectively. So, it looks to be about 6 years between the two events. (6 years = about 2190 days)
