The Hebrew Israelite calendar is 364 Days, NOT 354 of the Jewish lunar calendar. I compiled all the following locations that says the calendar is recorded to be 364 days:

Enoch 72:37 “And the year amounts to exactly 364 days.”
Enoch 74:10 “but change the year in exactly 364 days.”
Enoch 74:12 “the exact harmony of the world is completed in the separate 364 stations of the world.”
Enoch 81:6-7 “And the year is completed in 364 days.”
Enoch 81:11 “who divide the months and the years into 364 days”
Jubilees 6:32 “And command you the children of Israel that they observe the years according to this reckoning 364 days, and these will constitute a year”
Jubilees 6:38 “the year 364 days only"
Dead Sea Scrolls (Genesis Apocryphon) 4Q252, fr. I "On that day Noah went forth from the ark at the end of a full year of three hundred and sixty-four days"
Dead Sea Scrolls (Sectarian Calendar) 4Q3943-71 i "And the year Is complete: three-hundred and si[xty-four] days"
