how do u change the season on pokemon black and white?

It changes automatically, once every month.

First off, SPELL CORRECTLY!

Second, it changes every month.

Dear pokemon FAN! :P just change the ماہ on your DS January is srping Febuary is summer march is fall and april is winter and its goes like that may would be spring and june would be summer

The seasons change once a month. Also, آپ can only go to certain placees and catch certain pokemon in a certain season.

go to your system settings on your ds and change it to one ماہ ahead make sure before آپ do it آپ save in a building یا gate. when آپ turn it back on it should say its the same season but when آپ walk out it should change

It changes every month. I was wondering the same thing until I read the manual.

Well every two months یا so, it changes.
(Example: When it's March-April, it should be fall.) It's a very confusing process.
