Hello we are Nick Barkas and Ioannis Barkas from Greece. There is an
annoying error in the date command for quite some time when using
Greek locale.
If date is instructed to print month and day of month, the translation
is wrong and looks funny...
 You have to be able to write Greek in order to understand it and
since the bug exists we assume no one from coreutils developers knows
Greek.
 As a result we will explain every month in detail as it will be Greek
to you. Remove "LC_TIME=el_GR.UTF-8" from the commands to get the date
in English.

This is what you get with "B Y" (month year), which is correct:
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-01-01"
Ιανουάριος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-02-01"
Φεβρουάριος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-03-01"
Μάρτιος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-04-01"
Απρίλιος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-05-01"
Μάιος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-06-01"
Ιούνιος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-07-01"
Ιούλιος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-08-01"
Αύγουστος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-09-01"
Σεπτέμβριος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-10-01"
Οκτώβριος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-11-01"
Νοέμβριος 2015
$ LC_TIME=el_GR.UTF-8 date +"%B %Y" -d "2015-12-01"
Δεκέμβριος 2015

This is what you get with "d B Y" (month year), which is wrong:
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-01-01"
01 Ιανουάριος 2015
damn@rsee:~$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-02-01"
01 Φεβρουάριος 2015
damn@rsee:~$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-03-01"

Here is what the date command should print with "d B Y" (month year),
in el_GR.UTF-8 locale:
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-01-01"
01 Ιανουαρίου 2015
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-02-01"
01 Φεβρουαρίου 2015
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-03-01"
01 Μαρτίου 2015
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-04-01"
01 Απριλίου 2015
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-05-01"
01 Μαίου 2015
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-06-01"
01 Ιουνίου 2015
$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-07-01"

$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-09-01"

$ LC_TIME=el_GR.UTF-8 date +"%d %B %Y" -d "2015-10-01"
01 Οκτωβρίου 2015

In Greek language things are different and complex compared to
English. We have accents (τόνους) for most words and words are not
fixed but can dynamically change depending on context.
When the month is accompanied by a day of month the accent (Greek
tonos/τόνος) changes and ...ος becomes ...ου. To fix this, use the
correct translations for months, if and only if %B
 and %d are used together. If the month is called with no day (%d)
using "%B" or if the month is called with "%d %b" or "%b" leave the
translations as they are.
Since there are many computer-science oriented Greek universities and
so many Greeks around the world, we are amazed that no one fixed it so
far.
We must also inform you that this silly bug of yours has been seen in webpages.
