A year is the highest ordinary division of time and is associated with the sun’s return or revolution. The Hebrew year was solar while the month was lunar, with adjustment made by intercalation. The term may also be expressed by words meaning return or days.
Israel reckoned the year in two ways: by a sacred calendar beginning around the vernal equinox with Abib, and by a civil calendar beginning around the autumnal equinox. The supplied material also notes that Tisri is now the beginning of the Jewish year.
The ancient Egyptians divided the year into twelve months of thirty days, adding five days to complete the solar revolution. Hebrew reckoning combined a lunar month with a solar year through intercalation.
