I Know the Liturgical Name for 'LGM 1 Day'

I am presently shopping at Target but after reading Irenaeus' attack against the Marcosian practices all last night I realized that he informs us what the Alexandrian heretics called the day Christ was baptized by Jesus thirty days before the crucifixion. Just read the passage in chapter 20 Book II of Against the Heresies yourself.
It was called the day of recompense (Isaiah 61:2 LXX). I am absolutely certain of this. Irenaeus says the Marcosians have an unnatural order to their practice. The day of recompense should FOLLOW the year of favor and not the other way around.

And just think about 'the redemption' beginning with a day of recompense. It all makes sense now.

UPDATE the whole system here has been confirmed! The Jewish tradition has ALWAYS identified Purim as the "day of vengeance" (Isa 61:2 Hebrew). It develops from the description in Esther 9:2 - 17 and elsewhere. It's all downhill from here. The structure for identifying the thirty day period between "the day of vengeance" and Passover as "the redemption" was preexistent to the Alexandrian community's application of the pattern with regards to the narrative of Secret Mark based on the LXX of Isaiah.

Indeed Jewish communities CONTINUED to venerate the thirty day redemption period long after the establishment of Christianity as we read:

The fourteenth day of Adar was decreed as a day of vengeance on the enemies of the Jews ... Purim became a symbol for miraculous redemption from decrees and persecutions for the Jews. Different communities instituted "small Purims ( Purim Katan ) to commemorate their own deliverance.

More later ...
