POETS day is a term used by workers in the United Kingdom and Australia to refer jocularly to Friday as the last day of the work week. The word "POETS" is an acronym for "Piss off early, tomorrow's Saturday": hence Friday becomes "Poets day". It is tradition to begin the POETS day at 3.30pm in the afternoon. Variations on this are "Punch out early, tomorrow's Saturday" (referring to a manual punch time clock), "Push off early, tomorrow's Saturday" and "Push off early, tomorrow's Sunday" (based on the old 6-day work week). Another usage is in the slang of the United States Navy as an acronym for "Piss on electronics, tomorrow's Saturday". It is used by people in electronics ratings and refers to any day before the start of the weekend as a period without working time to be spent at paid occupational labour.
It also is a backronym, to be read as in "A Poets Day Dream."
