We don’t need to search for Jubilee dates – the last Jubilee was proclaimed by Jesus at His first coming.
Luke 4:18-21 “The Spirit of the Lord is on me, because he has anointed me to proclaim good news to the poor. He has sent me to proclaim freedom for the prisoners and recovery of sight for the blind, to set the oppressed free, to proclaim the year of the Lord’s favour.” Then he rolled up the scroll, gave it back to the attendant and sat down. The eyes of everyone in the synagogue were fastened on him. He began by saying to them, “Today this scripture is fulfilled in your hearing.”
The expression of Luke 4:19 and Isaiah 61:2 “year of the Lord’s favour” clearly alludes to the jubilee year in Leviticus (Lev 25,10-13)
Jesus proclaimed a Jubilee. Instead of being one year it was 7 years. It was proclaiming the last ‘7’ of Daniel’s 70 week prophecy, the 69th week of years.
Dan 9:24 Seventy ‘sevens’ are decreed for your people and your holy city to finish transgression, to put an end to sin, to atone for wickedness, to bring in everlasting righteousness, to seal up vision and prophecy and to anoint the Most Holy…v 27 He will confirm a covenant with many for one ‘seven.’ In the middle of the ‘seven’ he will put an end to sacrifice and offering.”
There is a gap in the last 7 from the time Jesus was “cut off” until the 3.5 years of witness prior to His return (as per Rev. 11).
The Year of Jubilee in Lev. 25:10-13
“ ‘Count off seven sabbath years—seven times seven years—so that the seven sabbath years amount to a period of forty-nine years. Then have the trumpet sounded everywhere on the tenth day of the seventh month; on the Day of Atonement sound the trumpet throughout your land. Consecrate the fiftieth year and proclaim liberty throughout the land to all its inhabitants.
