Based on the most recent renewed moon sightings from Jerusalem on 11 February 2024, the most likely candidate for Nissan 1 is about 9-10 May, 2024
If Nissan 1, were to be April 9-10 2024, THEN all the Tribes of Israel would need their Barley Harvest started and completed by Nissan 1, minimum, in order to do the walk to Jerusalem for the Feast.
It is highly unlikely, but not impossible, that all the Northern and North Eastern Tribes of Israel could have this completed by April 9-10 considering typical weather patterns, rain cessation, etc.
All Tribes of Israel are required to NOT show up to the Feast empty handed, meaning their Barley Harvest must be complete so they can calculate the size of their FirstFruits tithe.
