Friday is sometimes called “POETS Day,” an acronym for “Piss/Punch/Push Off/Out Early, Tomorrow’s Saturday.” That is, work should be done early, so that one can celebrate Saturday (a day off work).
 
“‘Poet’s day’ (piss off early, tomorrow’s Saturday)” was published in The Guardian (London, UK) in 1977, in a story about Calcutta (Kolkata), India. “Push Off Early, Tomorrow’s Saturday” was cited in a 1981 newspaper. The “POETS Day” term is mostly unknown in the United States.
 
   
Wikipedia: POETS Day
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).
