ante diem vii idus apriles
ludi Megalesia (day 4)
30 A.D. — crucifixion of Jesus (one reckoning according to the astronomical estimates)
303 A.D. — martyrdom of Calliopus at Pompeiopolis
310 A.D. — martyrdom of Peleusius at Alexandria
This is a fascinating question which the Holy Father also delved into in Jesus of Nazareth (Vol. 2). The Holy Father’s book, by the way, would be a great tool for your preparation for a good observance of Holy Week. Think about it.
I found an interesting article online about the dating of the Crucifixion which takes into account the probably reference to an eclipse. Check it out.
The writer states:
The main textual evidence for the time of the crucifixion has been reviewed and we have concluded that only 2 dates, 7 April, A.D. 30 and 3 April, A.D. 33, fit the main pieces of evidence for when Christ died. Other textual evidence, more difficult to interpret correctly, strongly favours Friday, 3 April, A.D. 33 as the date of the crucifixion.
So… probably not today… but maybe it was today.
