Soy_Wink is totally correct. In Spanish, the adjetives must match with their relatives noums in gender and number. So:
Buena noche - fem-sing & fem-sing (this sentence is not really common but it is only an example)
Buenas noches - fem-pl & fem-pl
Buen día - male-sing & male-sing
Buenos dias - male-pl & male-pl
The meaning of buenos or buenas is the same but which to use depends on whether the noun is masculine feminine. In this example, bueno is a masculine adjective and it is used to describe masculine noun "día", and same principle for buena and noche.
Hope it is helpful.
