The Hebrew-Calendar Month of Jesus' Death
TimeLine Note:

     Jesus was born on Nisan 6, 2 BC and He died at age 34 years 8 days on Nisan 14, 33 AD - the 14th Day of God's 5th Millennium.
     This chart may be helpful with calculations involving both BC and AD dates.
Jesus sacrificed His life precisely as the animal sacrifice was done for the Old Testament Passover celebration:
     The sacrificial animal ... was slain on the eve of the Passover,
     on the afternoon of the 14th of Nisan, after the Tamid sacrifice
     had been killed, i.e., at three o'clock....

On the lunar Jewish Calendar, this is the afternoon of Nisan 14, hours prior to the beginning at twilight, of seven days of Passover celebrations, and then after sunset (the evening which begins Nisan 15) the Seder meal kicks off the seven-day Passover Festival and Feast of Unleavened Bread.

TimeLine Note:
If you understand why Jesus had  to become a man, had  to come to Earth and had  to fulfill His mission; and if you understand what that mission was; then you likely know that Jesus came here to fulfill the Old Testament - the Old Covenant that God made with Israel.
 
This fulfillment also applied to the Law of the Old Covenant, which was but a foreshadow of what lay ahead - Jesus and His New Covenant.
 
Jesus became the Spotless Lamb, taking the place of the spotless sacrificial lamb of the Passover, and died in place of the sinner, making the payment for sin that we, just like that symbolic lamb, could never have made.
 
Fulfilling Passover meant fulfilling it in detail, including the timing.  The lamb was to be sacrificed on the 14th day of the Jewish first month, Nisan (also Abib), just before dusk, and just before evening, which begins the new day of Nisan 15.  So Jesus needed to be sacrificed at that same time.
 
He also needed to rise three days later as He said He would, and that day needed to be the Day of First Fruits, on the First Day of the Week.
TimeLine Note:

With new information gathered in 2024, and the greater understanding this has brought to the subject of God's Jubilee and the Cycle of Jubilee-Celebration, we now know that 2 BC marked the beginning of the third septennate of Israel's 10th (and final) Jubilee of the period of the Second Temple.

We also now know that 33 AD was the very year of Israel's 10th Jubilee of the period of the Second Temple.

Jubilee was God's Year of Debt-Forgiveness (Lev 25) - the year when liability was pardoned and slaves were set free - precisely what our Lord and Redeemer accomplished for the entire world, with His Life, Death and Resurrection!
