her gecenin bir gündüzü vardýr....

 My try

Every evening´s a daytime that has arrived.   (??)

thanks! dont really know what hes meaning there

I don´t know if it´s right.If you google it you get loads of hits.

her gecenin bir gündüzü vardýr....

I think the var is used posessive.  her gece-n-in (bir) gündüz-ü var(dýr)

The -dýr is only used to emphasize the ´var´

Every night has a daytime.   (could it mean: after every night there´s always another day???)

That was my first thought but I couldn´t make it make sense.Mine was rather poetic,though erroneous.

every night has a day (there is always a day/sunshine after the night/darkness)
