The Romans certainly had a calendar but it had only 10 months and the year was 304 days. Any date written down at the time in relation to Christ's crucifixion (which is noted as an historical event regardless of whether you give it religious significance) would not equate at all with the later Julian calendar (and the later still Gregorian).

It was the Synod of Whitby which decided on the rather convoluted calculation for Easter and it has connections with the Jewish lunar calendar and the month in which Passover is celebrated.

Was Jesus Christ a prince of Peace? Not so much as the Victorians reinvented him to be I don't think (gentle Jesus meek and mild and all that rot). He was an historic figure - a revolutionary in difficult times when his country was occupied by Rome and not quite the mysterious, shadowy being often portrayed in films and on TV.
