sure,

jeden, dwa, trzy, cztery, pięć,
sześć, siedem, osiem, dziewęć,

and then to count

raz, dwa, trzy, czterty, pięć,
sześć, siedem, osiem, dziewięć,
dziesięńć...

but in terms of months?

january, february, march,
april, may, june, july, august,
september, october,  november,
december,

styczen, luty, marzec, kwiecień,
maj...
                      czerwiec...
    grudzień..­.
                        
       i can't remember the months of
the year in native...

i'm missing the months:

july (lipiec),
            sierpiec (august),  
    wrzesień (september),
pazdziernik (october),
                listopad (november)...

diacritical markings are clear
indications of syllables...

         and yes,
they also encompass syllable but also
grapheme compounds,
akin to the sh / ch via š / č...
     or, to speak the orthodox...
     or... via reinterpreting the
sz = sh / cz = ch -
  well the caron of the stressed letter at first,
becomes the latter,
with the circumflex -

   ẑ = š = č -

         albeit more unlike french...

                z
             /    \
         š-s      c-č
             \   /
                ẑ              diamond.

szaken, not stirred -
   shaken, not stirred.
                      
                 which is why find the caron z
ž improbable to configure,
   given the chance of it being accompanied
with either S, shackle,
   or C, choke, whereby the caron
belong to either S or C, but not the Z,
in what would otherwise be H
in english...

i pity the english for not having applied
diacritical marks,
   and i also pity the russians
for having applied a diacritical mark
  that's mere a softening of a letter...
   i.e. ВЬ - bjee rather than b'ah...
               etc. -
   it's almost like both empires
didn't acknowledge an above, or a below,
in having letters coordinate,
           so they competed for a space-race.
it's worthwhile having that sort
of oops to look smart, when you've
ended up being stupid.
