This was the
eighth of the priestly courses of ministration in the Temple (I Chron. 24:10), and occurred, as did the others, twice in the year.
The "Courses" were changed every week, beginning each with a Sabbath. The reckoning commenced on the 22nd day of Tisri or Ethanim (Ap. 51. 5). This was the eighth and last day of the Feast of Tabernacles = the "Great Day of the Feast" (John 7:37), and was a Sabbath (Lev. 23:39)
The first course fell by lot to Jehoiarib, and the eighth to Abia or Abijah (1Chron. 24:10).
Bearing in mind that
all the courses served together at the three Great Feasts, the dates for the two yearly "ministrations" of Abiah will be seen to fall as follows:
The first (*1) ministration was from 12 - 18 Chisleu = December 6 - 12.
The second ministration was from 12 -18 Sivan = June 13 - 19.
The announcement therefore to Zacharias in the Temple as to the conception of John the Baptist took place between 12 - 18 SIVAN (June 13 -19), in the year 5 B.C. After finishing his "ministration", the aged priest "departed to his own house" (Luke 1:23) which was in a city (*2) in "the hill country" of Juda (verse 39).
The day following the end of the "Course of Abia" being a Sabbath (Sivan 19), he would not be able to leave Jerusalem before the 20th
