The situation of this letter (2 Macc 1:7-1:9)

“In the reign of King Demetrius,

In the one hundred and sixty-ninth year,

We Jews wrote to you.

In the critical distress that came upon us,

In those years

After Jason and his company

Revolted from the holy land and the kingdom.

He burned the gate and shed innocent blood.

We prayed to the Lord.

We were heard.

We offered sacrifice and cereal offering.

We lighted the lamps.

We set out the loaves.

Now see that you keep the festival of booths

In the month of Chislev,

In the one hundred and eighty-eighth year.”

Here is the reason for the letter. They want the Jews in Egypt to celebrate the festival of Booths in 124 BCE in the month of Chislev, the 188th year. Apparently this is not the first letter since there is a reference to an earlier letter around 143 BCE, the 169th year mentioned here, when King Demetrius II was the Seleucid leader. All these calendar dates are from the beginning of this Seleucid Empire in 312 BCE. The distress was the capture and murder of Jonathan Apphus, the son of Mattathias in 143 BCE. Jason was the brother of the high priest Onias, who turned on the Maccabees. The destruction and shedding of innocent blood can be found in 1 Maccabees, chapter 1. However, under Simon, they were able to recover and rebuild the Temple. Thus they were asking the Jews in Egypt to celebrate with them the feast of Booths in Chislev. However, the normal time of festival of Tents or Booths, according to Leviticus, chapter 23, was in the 7th month, 1 week after the Day of Atonement. Clearly this work must have been written after 124 BCE.
