in such a snowy day还是on such a snowy day
这两种说法那一种对?

on such a snowy day是对的

on
具体某一天用 on 如 on Friday on June 24th 注意:**的晚上,早上也用on 如:on a windy night,on a snowy morning; 但是没有形容词时用 in 如 in the morning; in the evening
某月 或者某年 用 in in June ; in 2011 但是同时有年月日的话,以小单位天为主:如 on June 24th,2011
几点用 at at 9 o'clock
