Of course this Egyptian year bore no fixed relation to the actual lunar months or solar year, nor therefore to the Jewish year, which was related to both.
In connecting the lunar month with the solar year, the framers of the ecclesiastical calendar adopted the period of Meton, or lunar cycle, which they supposed to be exact.
The first month of the Luni-solar year, by reason of the Intercalary month, began sometimes a week or a fortnight before the Equinox or Solstice, and sometimes as much after it.
That the Israelites used the Luni-solar year is beyond question.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "solar year" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
