Chanukah always overlaps with at least one Shabbat (if not two), and since Chanukah begins on the 25th of Kislev and lasts for eight days, the holiday always coincides with the celebration of Rosh Chodesh Tevet. (Today, 30 Kislev, and tomorrow, 1 Tevet, are both Rosh Chodesh.) This is significant, because both Rosh Chodesh and Shabbat were loathed by the Syrian-Greeks and their observances were outlawed.

The very first commandment that the Jewish people received as a nation was, “This month shall be yours as the first of months” (Exodus 12:1-2), instructing the Jews to sanctify the beginning of each new month. The Syrian-Greeks felt threatened by the Jewish concept of Divinely ordained time, since the sanctification of the month was based on the sighting of the new moon, rather than by a humanly calculated number of days.

The Syrian-Greeks were against the observance of Shabbat, not because it sanctified time, but because it was a day of rest, a day of no creative labor. “Six days shall you work and do all your labor, but the seventh day is Shabbat for the Lord your God. On it, you shall do no [creative] work” (Exodus 20:9-10). This contradicted the essence of Hellenistic culture, through which the Syrian-Greeks proclaimed their control over the world. The Jewish idea of taking one day off to demonstrate belief in God’s control of the world, negated the Syrian-Greek belief in the ultimate power of the individual.

That the Jews held fast to their belief in one unseen God who knows and controls the entire world infuriated the Syrian-Greeks, who wished to show that humankind was in control of nature. The Syrian-Greeks therefore prohibited the Jews, under penalty of death, from sanctifying the new moon (Rosh Chodesh) and keeping the Sabbath.
