Re: quarter code for date

A year of weeks (ISO) may be 52 or 53, depending on when the first Thursday of 
the month lands.
Therefore a quarter of a year may include 13 or 13.5 weeks. (one definition).
The other, by your simple shell script, it provides a second definition, based 
on the calendar.
One more ponderable, Do we take days in the year and use 1 Jan as the start of 
a quarter, or the  first week to be the one containing the Sunday that first 
precedes or has  1 January   (Dec 27th 2016)?
