While yes human gestation is 280 days that is counted from the beginning of the month she becomes pregnant not from conception. At conception she is counted as being at 14 days gestation thus the time from conception to birth is 266 days not 280. You can look this up in biology textbooks or ask a doctor. Or go to https://en.wikipedia.org/wiki/Prenatal_developmentThat is why if he was conceived on the 7th night of Hanukkah (Tevet 1 in 06 BC) he would’ve been born on trumpets (Tishri 1) on 5 BC. Makes sense the trumpets heralding the messiahs arrival. Many mistakenly point to tabernacles for the birth but they are using 280 days from conception not 266 (trumpets is 14 days BEFORE tabernacles). He would have had to have been crucified on a Thursday Passover in 30 AD. You can’t go on the calendar converter sites to check because they base their findings on the current rules for the jewish calendar which is not how the calendar was determined in Jesus day. Then they used the sighting of the new moon. Again make sense since 40 years later, 70 AD, was the destruction of the temple.
