King Demetrius I allows all the Jewish feast days (1 Macc 10:34-10:35)

“All the festivals, Sabbaths, new moons, appointed days,

The three days before a festival

And the three after a festival

All these days will be days of immunity and release

For all the Jews who are in my kingdom.

No one shall have authority to exact anything from them

Or annoy any of them about any matter.”

All the Jewish people could celebrate their festivals, Sabbath days, new moons or other appointed days with full immunity. In fact, they could have 3 days before and 3 days after the festival to be released from work. This applied to all the Jews in the kingdom, not just those in Judea. No one would have any authority over these festivals. No one should annoy them about these feast days. This was total religious freedom, as had been common in the empire prior to King Antiochus IV.
