Historical origins
In the earliest times the Hebrew year began in autumn with the opening of the economic year. There followed in regular succession the seasons of seed-sowing, growth and ripening of the corn (here meaning any grain) under the influence of the former and the latter rains, harvest and ingathering of the fruits. In harmony with this was the order of the great agricultural festivals, according to the oldest legislation, namely, the feast of unleavened bread at the beginning of the barley harvest, in the month of Aviv; the feast of harvest, seven weeks later; and the feast of ingathering at the going out or turn of the year. "Aviv" literally means "Spring". (See Exodus 23:14-17; Deuteronomy 16:1-16).
It is likely that the new year was celebrated from ancient times in some special way. The earliest reference to such a custom is, probably, in the account of the vision of Ezekiel (Ezek 40:1). This took place at the beginning of the year, on the tenth day of the month (Tishri). On the same day the beginning of the year of jubilee was to be proclaimed by the blowing of trumpets (Lev 25:9). According to the Septuagint rendering of Ezek 44:20, special sacrifices were to be offered on the first day of the seventh month as well as on the first day of the first month. This first day of the seventh month was appointed by the Law to be "a day of blowing of trumpets". There was to be a holy convocation; no servile work was to be done; and special sacrifices were to be offered (Lev 23:23-25; Num 29:1-6). This day was not expressly called New-Year's Day, but it was evidently so regarded by the Jews at a very early period.
